—

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this

or any other appliance.

—

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s

instructions.

• If you cannot reach your gas supplier, call the fire department.

—

Installation and service must be performed by a qualified installer, service agency, or the

gas supplier.

WARNING: This is an unvented gas-fired heater. It uses air (oxygen) from the room in which it

is installed. Provisions for adequate combustion must be provided. Refer to page 3 of this

manual.

This appliance may be installed in an aftermarket* manufactured (mobile) home, where not

prohibited by state or local codes.

* Aftermarket: Completion of sale, not for purpose of resale, from the manufacturer

This appliance is only for use with the type of gas indicated on the rating plate. This appliance

is not convertible for use with other gases.

WARNING: This heater shall

not be installed in a confined

space unless provisions are pro-

vided for adequate combustion

and ventilation air. Read the fol-

lowing instructions to insure

proper fresh air for this and other

fuel-burning appliances in your

home.

Grill Guard

Today’s homes are built more energy effi-

cient than ever. New materials, increased

insulation, and new construction methods

help reduce heat loss in homes. Home own-

ers weather strip and caulk around windows

and doors to keep the cold air out and the

warm air in. During heating months, home

owners want their homes as airtight as pos-

sible.

While it is good to make your home energy

efficient, your home needs to breathe. Fresh

air must enter your home. All fuel-burning

appliances need fresh air for proper com-

FEATURES

Exhaust fans, fireplaces, clothes dryers, and

fuel burning appliances draw air from the

house to operate. You must provide ad-

equate fresh air for these appliances. This

will insure proper venting of vented fuel-

burning appliances.

Install and use heater with care. Follow all

local codes. In the absence of local codes,

use the latest edition of The National Fuel

Gas Code ANSI Z223.1, also known as

NFPA 54*.

Safety Pilot

This heater has a pilot with an Oxygen

Depletion Sensor Shutoff System (ODS).

All spaces in homes fall into one of the three

following ventilation classifications:

UNPACKING

1. Remove heater from carton.

1. Unusually Tight Construction; 2. Uncon-

2. Remove all protective packaging ap-

and provide adequate ventilation.

3. Check heater for any shipping damage.

If heater is damaged, promptly inform

The air that leaks around doors and win-

combustion and ventilation. However, in

buildings of unusually tight construction,

you must provide additional fresh air.

Unusually tight construction is

defined as construction where:

Space: Includes the room in which you

will install heater plus any adjoining rooms

with doorless passageways or ventilation

grills between the rooms.

The space in the above example is a con-

fined space because the actual Btu/Hr used

is more than the maximum Btu/Hr the space

can support. You must provide additional

fresh air. Your options are as follows:

C. Install a lower Btu/Hr heater, if lower

Btu/Hr size makes room unconfined.

2. Divide the space volume by 50 cubic

feet to determine the maximum Btu/Hr

the space can support.

If the actual Btu/Hr used is less than the

maximum Btu/Hr the space can support, the

space is an unconfined space. You will need

no additional fresh air ventilation.

and contaminants. This keeps them from

going into heater controls. If sediment trap

is not installed or is installed wrong, heater

may not run properly.

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 heater valves.

CAUTION: Never connect

CAUTION:Usepipejointseal-

The installer must supply an external regu-

incoming gas pressure between 11 and 14

inches of water. If you do not reduce incom-

ing gas pressure, heater regulator damage

could occur. Install external regulator with

Check pilot flame pattern and burner flame

pattern often.

WARNING: Turn off heater

and let cool before cleaning.

PILOT FLAME PATTERN

Figure 18 shows a correct pilot flame pat-

tern. Figure 19 shows an incorrect pilot

flame pattern. The incorrect pilot flame is

not touching the thermocouple. This will

cause the thermocouple to cool. When the

thermocouple cools, the heater will shut

down.

CAUTION: You must keep

control areas, burner, and circu-

lating air passageways of heater

clean. Inspect these areas of

heater before each use. Have

heaterinspectedyearlybyaquali-

fied service person. Heater may

needmorefrequentcleaningdue

to excessive lint from carpeting,

bedding material, etc.

NOTICE: Do not mistake orange

flames with yellow tipping. Dust

or other fine particles enter the

heater and burn causing brief

patches of orange flame.
