WARNINGS

IMPORTANT: Read this owner’s manual carefully and completely

before trying to assemble, operate, or service this heater. Improper

use of this heater can cause serious injury or death from burns, fire,

explosion, electrical shock, and carbon monoxide poisoning.

WARNING ICON G001

DANGER

Carbon monoxide poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning

resemblethe flu,withheadaches,dizziness,or nausea.If youhavethesesigns,the

heater may not be working properly. Getfreshairat once! Have heater serviced.

Some people are more affected by carbon monoxide than others. These include

pregnant women, persons with heart or lung disease or anemia, those under the

influence of alcohol, and those at high altitudes.

Natural Gas: Natural gas is odorless. An odor-making agent is added to natural

gas. The odor helps you detect a natural gas leak. However, the odor added to

natural gas can fade. Natural gas may be present even though no odor exits.

Make certain you read and understand all warnings. Keep this manual for

reference. It is your guide to safe and proper operation of this heater.

FEATURES

Safety Device

This heater has a pilot with an Oxygen Depletion Sensor Shutoff System (ODS).

The ODS/pilot is a required feature for vent-free heaters. The ODS/pilot shuts off

the heater if there is not enough fresh air.

Piezo Ignition System

This heater has a piezo ignitor. This system requires no matches, batteries, or other

sources to light heater.

Thermostatic Heat Control

(Thermostat Model Only)

Thermostat model has a thermostat sensing bulb and a control valve. This results in

the greatest heater comfort. This can also result in lower gas bills.

LOCAL CODES Install and use heater with care. Follow all local codes. In the absence of local

codes, use the latest edition of National Gas Code ANSI Z223.1, also known as

NFPA 54*.

Methods For Attaching Mounting Bracket To Wall

Only use last hole on each end of mounting bracket to attach bracket to wall. These

two holes are 16 inches apart from their centers. Attach mounting bracket to wall in

one of two ways.

1. Attaching to wall stud

2. Attaching to wall anchor

Attaching to wall stud This method provides the strongest hold. Insert mounting

screws through mounting bracket and into wall studs.

Attaching to wall anchor This method allows you to attach mounting bracket to

hollow walls (wall areas between studs) or to solid walls (concrete or masonry).

Decide which method better suits your needs. Either method will provide a secure

hold for the mounting bracket.

Marking Screw Locations

1. Tape mounting bracket to wall where heater will be located. Make sure mount-

ing bracket is level.

Attaching Mounting Bracket To Wall

Note:

Wall anchors, mounting screws, and spacers are in hardware package. The

hardware package is provided with heater.

Attaching to wall stud method

For attaching mounting bracket to wall studs

1. Drill holes at marked locations using 9/64" drill bit.

2. Place mounting bracket onto wall. Line up last hole on each end of bracket with

holes drilled in wall.

3. Insert mounting screws through bracket and into wall studs.

4. Tighten screws until mounting bracket is firmly fastened to wall studs.

Attaching to wall anchor method

For attaching mounting bracket to hollow walls (wall areas between studs) or solid

walls (concrete or masonry)

1. Drill holes at marked locations using 5/16" drill bit. For solid walls (concrete or

masonry), drill at least 1" deep.

2. Fold wall anchor as shown in Figure 7.

2. Mark screw locations on wall (see Figure 6).

Note:

Only mark last hole on each end of mounting bracket. Insert mounting

screws through these holes only.

3. Remove tape and mounting bracket from wall.

3. Insert wall anchor (wings first) into hole. Tap anchor flush to wall.

of heater (see Figure 10).

2. Mark screw locations on wall.

3. Remove heater from mounting bracket.

4. If installing bottom mounting screws into hollow or solid wall, install wall

anchors. Follow steps 1 through 4 under Attaching To Wall Anchor Method,

page 8.

If installing bottom mounting screw into wall stud, drill holes at marked loca-

tions using 9/64" drill bit.

5. Replace heater onto mounting bracket.

6. Place spacers between bottom mounting holes and wall anchor or drilled hole.

7. Hold spacer in place with one hand. With other hand, insert mounting screw

through bottom mounting hole and spacer. Place tip of screw in opening of wall

anchor or drilled hole.

CONNECTING

TO GAS

SUPPLY

NOTICE

A qualified service person must connect heater to gas supply.

Follow all local codes.

WARNING ICON G 001

WARNING

Never connect heater to private (non-utility) gas wells. This gas is

commonly known as well-head gas.

IMPORTANT:

Check gas line pressure before connecting heater to gas line. Gas

line pressure must be no greater than 14 inches of water. If gas line pressure is

higher, heater regulator damage could occur.

Installation must include a manual 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 heater (see Figure 11, page 11).

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant

from going into pipe. Excess sealant in the pipe could result in clogged heater

valves.

WARNING ICON G001

CAUTION

Use only new, black iron or steel pipe. Copper tubing may be used

in certain areas. Check your local codes. Use pipe of 1/2" diameter

or greater to allow proper gas volume to heater. If pipe is too small,

undue loss of pressure will occur.

CAUTION

Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

WARNING ICON G 001

Install sediment trap in supply line as shown in Figure 11. Locate sediment trap

where it is within reach for cleaning. Locate sediment trap where trapped matter is

not likely to freeze. A sediment trap traps moisture 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.
