INSTALLATION PLANNING

NOTICE: Failure to follow these

instructionswillvoidthewarranty.

There are two basic types of direct-vent

installation:

Your Vanguard direct-vent fireplace has

been tested for a minimum 3' rise with a

maximum 10" wall thickness. The maxi-

mum horizontal run is 20' with 8' vertical

rise (see Installation for Horizontal Termi-

nation, pages 8 and 9). The maximum ver-

tical run is 30' (see Installation for Vertical

Termination, pages 12 and 13).

INSTALLATION

PRECAUTIONS

• Horizontal Termination

• Vertical Termination

Consultlocalbuildingcodesbeforebeginning

the installation. The installer must make sure

to select the proper vent system for installa-

tion. Before installing vent kit, the installer

must read this fireplace manual and vent kit

instructions.

It is important to select the proper length of

vent pipe for the type of termination you

choose. It is also important to note the wall

thickness.

For Horizontal Termination: Select the

amount of vertical rise desired. The horizon-

tal run of venting must have 1/4" rise for

every 12" of run towards the termination.

It is very important that the venting system

maintain its balance between the combus-

tion air intake and the flue gas exhaust.

Certain limitations apply to vent configura-

tions and must be strictly followed.

Only a qualified service person should in-

stall venting system. The installer must fol-

low these safety rules:

A MDVGFK ground floor horizontal vent

kit is specifically designed for common

horizontal installations in manufactured

(mobile) homes. Additional horizontal in-

stallationsaredescribedonpages10and11.

All vent kits and components are listed on

pages 15 and 16.

• Wear gloves and safety glasses for

protection

• Use extreme caution when using ladders

or when on roof tops

• Be aware of electrical wiring locations

in walls and ceilings

The following actions will void the war-

ranty on your venting system:

Note: If an offset is needed to avoid ob-

structions, you must support the vent pipe

every 3 feet. Use wall straps for this pur-

pose (see Figure 21). Whenever possible,

use 45° elbows instead of 90° elbows. The

45° elbow offers less restriction to the

flow of the flue gases and intake air.

Flat Ceiling Installation

VENTING

1. Cut a 10" square hole in the ceiling us-

ing the locating hole as a center point.

The opening should be framed to

10"x10" (254mm x 254mm) inside di-

mensions, as shown in Figure 12 on

page 9 using framing lumber the same

size as the ceiling joists. If the area

above the ceiling is an insulated ceil-

ing or a room, nail firestop from the

top side. This prevents loose insulation

from falling into the required clearance

space. Otherwise, install firestop below

the framed hole. The firestop should be

installed with no less than three nails

per side (see Figure 22).

the vent pipe to combustible materials.

When installing the flashing on a metal

roof we require that putty tape is used

between the flashing and the roof. The

flashing must be secured to the roof us-

ing #8 x 3/4" screws and then sealed

with roof coating to prevent leakage

through the screw holes. A roof coat-

ing must also be applied around the pe-

rimeter to provide a proper seal.

1. Determine the route your vertical vent-

ing will take. If ceiling joists, roof

rafters, or other framing will obstruct

the venting system, consider an offset

(see Figure 21) to avoid cutting

loadbearing members. Note: Pay spe-

cial attention to these installation in-

structions for required clearances (air

space) to combustibles when passing

through ceilings, walls, roofs, enclo-

sures, attic rafters, etc. Do not pack air

spaces with insulation.Also note maxi-

mum vertical rise of the venting sys-

tem and any maximum horizontal off-

set limitations. Offsets must fall within

the parameters shown in Figure 8 on

page 6.

2. Assemble the desired lengths of pipe and

elbows necessary to reach from the fire-

place flue up through the firestop. All

connections must be sealed with high

temperature silicone sealant as specified

in the second warning on page 7. Be sure

all pipe and elbow connections are fully

twist-locked (see Figure 11, page 8).

6. Continue to add pipe sections until the

height of the vent cap meets the mini-

mum building code requirements de-

scribed in Figure 8 on page 6. Note:You

must increase vent height for steep roof

pitches. Nearby trees, adjoining rooflines,

steep pitched roofs, and other similar fac-

tors may cause poor draft or down-draft-

ing in high winds. Increasing the vent

height may solve this problem.

7. Twist-lock the vent cap onto the last

section of vent pipe and seal outer pipe

connection with high temperature sili-

cone sealant as specified in the second

warning on page 7.

2. Set the fireplace in desired location.

Drop a plumb line down from the ceil-

ing to the position of the fireplace exit

flue. Mark the center point where the

vent will penetrate the ceiling. Drill a

small locating hole at this point.

3. Cut a hole in the roof using the locating

hole as a center point. (Cover any ex-

posed open vent pipes before cutting

hole in roof.) The 10"x10" hole must

be measured on the horizontal; actual

length may be larger depending on the

pitch of the roof. There must be a 1"

clearance from the vent pipe to combus-

tible materials. Frame the opening as

shown in Figure 12 on page 9.

Drop a plumb line from the inside of

the roof to the locating hole in the ceil-

ing. Mark the center point where the

vent will penetrate the roof. Drill a

small locating hole at this point.

4. Connect a section of pipe and extend

up through the hole.

INSTALLING GAS PIPING TO

FIREPLACE LOCATION

Apply pipe joint sealant lightly to male

threads. This will prevent excess sealant

from going into pipe. Excess sealant in pipe

could result in clogged fireplace valves.

WARNING: A qualified ser-

vice person must connect fire-

place to gas supply. Follow all

local codes.

Installation must include an equipment

shutoff valve, union, and plugged 1/8" NPT

tap. Locate NPT tap within reach for test

gauge hook up. NPT tap must be upstream

from fireplace (see Figure 40).

CAUTION:Usepipejointseal-

ant that is resistant to liquid pe-

troleum (LP) gas.

CAUTION: For propane/LP

units, never connect heater di-

rectly to the propane/LP supply.

This heater requires an external

regulator(notsupplied).Installthe

external regulator between the

heater and propane/LP supply.

Propane/LP

Supply Tank

We recommend that you install a sediment

trap/drip leg in supply line as shown in

Figure 40. Locate sediment trap/drip leg

where it is within reach for cleaning. Install

in piping system between fuel supply and

heater. Locate sediment trap/drip leg where

trapped matter is not likely to freeze. A

sediment trap traps moisture and contami-

nants. This keeps them from going into

fireplace gas controls. If sediment trap/drip

leg is not installed or is installed wrong,

fireplace may not run properly.

BURNERS

Continued

Figure 59 shows a typical flame pattern for

MBDV37 and MBDV41.

Glass must be cleaned periodically. During

start-up it is normal for condensation to

form on the inside of the glass causing lint,

dust, and other airborne particles to cling to

the glass surface. During initial start-up a

slight film may form on the glass due to

paint curing. The glass should be cleaned

several times with a non-ammonia, non-

dren and pets away from glass.

Conduct annual inspection of the venting

system following these guidelines:

1. Check areas of venting system that are

exposed to the weather for corrosion (rust

spots or streaks and, in extreme cases,

holes). Have these items replaced imme-

diately by a qualified service person.

If glass has been broken, carefully remove

glass door (see Removing/Replacing Glass

with a shop vac.

2. Remove the vent cap and shine a flash-

light into the vent. Remove any foreign

material.

CAUTION: Do not vacuum if

pieces are hot.

3. Check for evidence of excessive con-

densation. Continuous condensation

can cause corrosion of caps, pipes, and

fittings and can be caused by having

excessive lateral runs, too many elbows,

or exterior portions of the system be-

ing exposed to cold weather.
