WARNING: Due to high temperatures, the HEATER

should be located out of traffic and away from furniture

and draperies.

Fig. 2 Possible stove locations.

Clearance Requirements

The surface of the Heater Is hot when it is in use.

Young children should be watched carefully when

they are in the same room when the Heater is in use,

and they should be taught to avoid the hot surface.

Keep any objects that can burn well away from the

Heater, and observe the recommended clearances

that follow.

Minimum Clearances to Combustible Materials

Measure side clearances as shown in Figures 3 and 4

from the outer edge of the cast iron stove top. Measure

rear clearances from the outermost surface of the steel

rear skirt.

The Jefferson heater is approved for installation into an

alcove constructed of combustible materials to the

dimensions and clearances shown on the next page.

Locating the Stove

In choosing a location for the stove, consider:

• The location of outside walls;

The same clearances apply in a standard parallel instal-

lation.

• Where additional heat is needed:

• Where family members gather most often;

• The vent system requirements.

WARNING:

• Always maintain required

clearances (air spaces) to nearby combustibles

to prevent fire hazard. Do not fill air spaces with

insulation. All venting components must

maintain a 1" (25mm) clearance to combustible

materials. Maintain a 6” (150mm) clearance

when using single wall pipe.

NOTE: We do not recommend the use of wallpaper next

to this stove. Over time, radiant heat may cause the

wallpaper to shrink, or may adversely affect the binders

in the wallpaper adhesive.

• The gas appliance and vent system must be

vented directly to the outside of the building and

never be attached to a chimney serving a

separate solid fuel or gas-burning appliance.

• Refer to the manufacturer's instructions

included with the venting system for complete

installation procedures.

Vertical Termination - Direct Vent ONLY

Vent Termination Clearances

A vertical vent system must terminate no less than 8'

(2.44m) and no more than 40’ (12m) above the appli-

ance flue collar. A 2¹⁄₄" restrictor plate (supplied) must be

used, where specified, in all vertically terminated vent

systems. (Refer to Figure 8) NOTE: The restrictor plate

supplied with the vertical termination should be

discarded. Install restrictor plate supplied with the

stove directly at stove outlet. A vertically terminated

vent system must also conform to the following criteria:

When planning the installation, consider the location of

the vent terminal and clearances. Some of the most

common clearances to keep in mind are shown in Figure

10.

Important: All vent clearances must be maintained.

Check your vent termination clearances against

Figures 10 and 11.

The vent should be placed so that people cannot be

burned by accidentally touching the vent surfaces when

the stove is operating.

•

No more than two 90˚ elbows may be used.

Two 45˚ elbows may be substituted for one 90˚ elbow.

No more than six elbows may be used.

The vent termination should be located where it cannot

be damaged by such things as automobile doors, lawn

mowers or snowblowers and it should be located away

from areas where it could become blocked by snow, etc.

•

Vent must rise a minimum of 2 feet before offset is used.

Termination height must conform to roof clearance as

specified in Figure 9.

Some considerations are:

•

Other nearby openings {within 9" (230mm)} through

which exhaust gas could reenter the building.

All vegetation within 3' (.9m) that may interfere with

the draft.

Other factors that influence where the installation will be

sited include the location of outside walls, where addi-

tional heat may be desired in the home, where the family

members gather most regularly, and perhaps most

importantly, the distance limitations of the venting

system.

Venting System Assembly - Natural Vent

General Information

For U.S. installations: The venting system must

conform with local codes and/or the current National

Fuel Gas Code, ANSI Z22.1.

The Jefferson Heater is shipped from the factory as a

Direct Vent Heater. It may be converted to a Natural

Vent heater by installing the Vermont Castings Model

Z31D00 FSDHAG Draft Hood Adapter.

For Canadian installations: The venting system must

conform to the current CSA B149.1 installation code.

The Jefferson Heater is approved for installation as a

Natural Vent. CFM Direct Vent pipe could be used

directly after the Draft Hood Adapter up to the ceiling,

then B-vent pipe must be used. Do not mix types of B-

vent pipe; use components from one maker or the

other. Follow the vent component maker’s instructions

exactly. The heater will also accept standard or

enamelled 7” (150mm) diameter pipe, around the Type

B venting, for decorative purposes only. (Fig. 32)

Install the Vent Pipe

Apply a bead of sealant around bottom end of inner

starter pipe (found in bag with logset) and attach to

stove. Apply a bead of sealant around top of inner

starter pipe and install the Z31D00 FSDHAG Draft

Hood according to Draft Hood instructions. (Fig. 33)

Attach the first section of venting to the draft hood.

Depending on the length of the individual venting

sections and the lengths of the decorative pipe (if

installed), you may need to slip the decorative pipe over

the venting sections before attaching upper sections to

lower ones. The sections of decorative pipe should be

oriented with their seams (if any) toward the wall;

sections usually do not need to be fastened at each

joint, other than slip sections. If the layout includes a

slip section, this should be the last section of pipe

visible in the room, at the ceiling. Complete the venting

according to the vent maker’s instructions.

NOTE: The restrictor plate supplied with the stove

is not used for Natural Vent applications.

The Jefferson stove, when installed as a Natural vent

heater, includes a vent safety switch. (Fig. 64, Page 33)

POSSIBLE CAUSES

CORRECTIVE ACTION

1. Spark ignitor will

not light

A. Defective or misaligned

electrode at the pilot

Using a match, light pilot. If pilot lights, turn off pilot and

push the ignitor button again. If pilot will not light, check

gap at electrode and pilot - it should be 1/8” to have a

strong spark.

B. Defective ignitor (push

button)

Push piezo ignitor button. Check for spark at electrode

and pilot. If there is no spark at the pilot, and electrode

wire is properly connected, replace ignitor.

A. Defective pilot generator

(thermocouple)

2. Pilot will not stay lit

after carefully

Check pilot flame. It must impinge on the thermocouple

or thermopile. NOTE: This pilot burner assembly uses

both a thermocouple and a thermopile. The thermo-

couple operates the pilot flame. Tighten the thermo-

couple. The thermopile operates the main valve (ON and

OFF). Clean and/or adjust pilot for maximum flame

impingement on thermocouple and thermopile.

following the

lighting instructions

B. Defective automatic valve

operator

Turn valve knob to ‘Pilot’. Maintain flow to pilot; millivolt

meter should read greater than 10mV. If the reading is

okay and the pilot does not stay on, replace the gas

valve. NOTE: An interrupter block (not supplied) must be

used to conduct this test.

A. Remote switch or wires

defective

Check rocker switch and wires for proper connection.

Use jumper wires across terminals at rocker switch. If

burner lights, replace rocker switch. If okay, use jumper

wires across rocker switch wires at the valve; if burner

lights, wires are faulty or connections are bad.

3. Pilot lights, no gas

to burner, valve

knob ON, remote

switch (rocker

switch) ON

B. Thermopile may not gener-

ate sufficient voltage

1. Be sure wire connections from thermopile at gas valve

terminals are tight and thermopile is fully inserted into

pilot bracket.

2. One of the rocker switch wires may be grounded.

Remove rocker switch wires from valve terminals. If

burner now stays lit, trace rocker switch wiring from

ground. It may be grounded to the appliance or the

gas supply line.

3. Check the thermopile with a millivolt meter. Take

reading at thermopile (“TP” and “TP/TH”) terminals of

gas valve. Should read 325 millivolts minimum while

holding valve knob depressed in PILOT position and

with rocker switch OFF. Replace faulty thermopile if

reading is below specified minimum.

C. Plugged burner orifice

Check burner orifices for debris, and remove.

D. Defective automatic valve

operator

Turn knob to ON, place rocker switch to ON, millivolt

meter should read greater than 10 mV. If the reading is

okay and the burner does not light, replace the valve.

A. Pilot flame may be too low

or high, (blowing or lifting),

causing the pilot to drop out

B. Possible blockage of the

vent terminal

4. Frequent pilot

outage

Clean and/or adjust pilot flame for maximum flame

impingement on thermocouple and thermopile.

Check the vent terminal for blockage.

Maintenance

Your Jefferson Gas Heater will provide years of service

with minimal upkeep. The following procedures will help

TURN THE PILOT OFF BEFORE PAINTING.

ALLOW THE HEATER TO COOL COMPLETELY

BEFORE PAINTING.

ensure that you stove continues to function properly.

Annual System Inspection

Have the entire heater and venting system inspected

annually by a qualified gas technician. Replace any

worn or broken parts.

Cleaning the Glass

WARNING: Let the glass cool completely before

attempting to clean.

Logset and Burner /

Cleaning and Inspection

It will be necessary to clean the glass periodically.

During start-up, condensation, which is normal, forms

on the inside of the glass and causes lint, dust and

other airborne particles to cling to the glass surface.

Also, initial paint curing may deposit a slight film on the

glass. It is therefore recommended that the glass be

cleaned two or three times with a non-ammonia house-

hold cleaner and warm water (we recommend gas

fireplace glass cleaner). After that the glass should be

cleaned two or three times during each heating season

depending on the circumstances present.

Cleanliness is critical to the proper function of the

heater. The logset and burner must all be kept free of

dust and unobstructed by debris. Inspect these areas

before each use and clean as necessary.

1. Turn the burner OFF and let the heater cool com-

pletely before cleaning.

2. Lift the Stove Front up and then swing the bottom

out to disengage it from the heater shell. (Fig. 59)

3. Carefully remove the glass and frame assembly and

place it out of the way on a flat, padded surface

such as a counter protected by a towel.

Clean glass after first two weeks of opera-

tion.

4. Carefully inspect the Logs for damage. Contact your

local dealer if any damage is evident. DO NOT

Glass Replacement

OPERATE THE HEATER WITH DAMAGED LOGS.

Replace glass only with Vermont Castings approved

parts. Refer to Page 34 for Replacement Parts. Refer

to Figure 60 and previous instructions for removal of the

damaged glass frame.

5. Use a soft bristled brush to sweep dust or debris

from the Logs, Pilot and Burner. Use care as the

logs are fragile and susceptible to damage. DO NOT

USE A VACUUM TO CLEAN THE LOGS OR

BURNER.

6. Replace the glass panel and frame assembly.

7. Replace the Stove Front.

Lift the plate

Care of Cast Iron

An occasional dusting with a dry rag will help keep the

painted surfaces looking new. Use high-temperature

stove paints, available through your local dealer, to

touch-up areas as needed. Clean areas to be painted

with a wire brush and be sure to cover the logs, burner

and valve assembly, glass and frame assembly. Apply

the paint sparingly; two light coats of paint will give

better results than a single heavy coat.

Clean porcelain enamel surfaces with a soft, damp

cloth. Do not use abrasive cleaning agents. If neces-

sary, use only a cleaning agent formulated especially

for use on porcelain enamel surfaces.

Vermont Castings Jefferson Direct Vent/Natural Vent Gas Heater

Inspect the Vent System Annually

Have the vent system inspected annually by a qualified

technician. Shut off the main gas supply before inspect-

ing the system. Both the inner exhaust pipe and the

outer combustion supply pipe must be checked to

confirm that they are unblocked and in good condition.

ST208a

Check the Gas Flame Regularly

Fig. 60 Release the latches to release the glass frame.

To ensure that the stove is operating properly, check

the flames periodically to confirm that they match

Figure 62. The flames will be blue during the first 15-20

minutes of operation, and will gradually turn to yellow

after that.

Gasket Replacement

The Jefferson Gas Heater uses a ‘tadpole’ type gasket

to seal between the glass panel and the frame. In time,

this gasket can become brittle and compressed and

should be replaced. New gasket is available from your

dealer.

Do not use your stove if the flame pattern differs from

that shown here. Contact your Vermont Castings dealer

or a qualified technician for help.

Shut off the gas supply and allow the stove to cool.

Wear safety goggles and a dust mask.

1. Remove the Front, Glass Frame and Glass Panel.

(Figs. 59 & 60) Remove the old gasket. Use a razor

blade to separate the glass and gasket from the

frame, and to clean the glass of any remaining

cement or bits of gasket. Use a cold chisel if neces-

sary.

2. Determine the correct length of gasket by laying it

out around the edge of the glass. Allow an extra 1 -

2” (25-50mm). Mark the spot to be cut. Use a utility

knife.

3. Starting on a long edge, remove about 6” of the

protective paper strip and apply the flat adhesive

face of the gasket around the outside-facing edge of

the panel. Continue around the panel, applying a

bout 6” at a time and being careful to not stretch the

material. Do not overlap the gasket ends. (Fig. 61)

ST234

Fig. 62 Correct flame pattern.

Stove Disassembly

4. Apply a thin bead of high temperature silicone

rubber sealant along the inside corner of the glass

frame, all around the perimeter. Place the flat

gasketed side of the glass panel back into the steel

frame. Pinch the rounded inside-facing gasket

material to bulk it up.

If there is ever a need to remove the firebox assembly

from the stove shell, support the firebox with solid

stands about 6” (150mm) tall under the left and right

outer edges of the firebox base. Do not set the firebox

assembly directly on the floor; this can damage the

control valve and/or the gas lines from the valve to the

firebox.

5. Replace the glass frame and front panel as previ-

ously described.

Before removing the firebox from the shell, disconnect

the on/off switch wires from the valve. If the assembly

includes the optional fan, disconnect the fan rheostat. If

the installation includes a wall thermostat, disconnect

the thermostat leads from valve.

Disconnection and reconnection to the gas line should

only be done by a qualified gas service technician.

Upon reinstallation, the vent system must be sealed to

the firebox as shown in the installation section, Page

14. Also be sure the logs are placed in the firebox

correctly, as shown on Page 20.
