PREPARING FOR INSTALLATION
AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a room or space unless the required volume
of indoor combustion air is provided by the method described in the Nation Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
All spaces in homes fall into one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 8-10 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
A conned space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw)
of the aggregate input rating of all appliances installed in that space and an unconning space as a
space whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate
input rating of all appliances installed in that space. Rooms connecting directly with the space in
which the appliances are installed*, through openings not furnished with doors, are considered a
part of the unconned space.
This heater shall not be installed in a conned space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air.
* Adjoining rooms are connecting only if there are doorless passageways or ventilation
grills between them.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and venti-
lation. However, in buildings of unusually tight construction, you must provide additional
fresh air.
Unusually tight construction is dened as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder
with a rating of one perm (6x10-11kg per pa-sec-m2) or less with openings gasketed or sealed
and
b) weather stripping has been added on windows that can be opened and on doors and
c) caulking or sealants are applied to areas such as joints around window and door frames,
between sole plates and oors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and at other openings.
If your home meets all of the three criteria above, you must provide additional fresh air.
See “Ventilation Air From Outdoors” (page 9). If your home does not meet all of the
three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

PREPARING FOR INSTALLATION
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned space.
Space: Includes the room in which you will install heater plus any adjoining rooms with
doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space Length × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft.(width) × 8 ft. (ceiling height) = 2560 cu. ft. (volume
of space)
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these
rooms to the total volume of the space.
2. Divide the space volume by 50 cu. ft. to determine the maximum BTU/hr the space can support.
_______ (volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support)
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum BTU/hr the space
can support)
3. Add the BTU/hr of all fuel burning appliances in the space.
Vent-free heater _________ BTU/hr
Gas water heater* ________BTU/hr
Gas furnace _____________BTU/hr
Vented gas heater ________BTU/hr Example:
Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr
Total = ____BTU/hr Total = 56,000 BTU/hr
*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used.
_______ BTU/hr (maximum the space can support)
_______ BTU/hr (actual amount of BTU/hr used).
Example : 51,200 BTU/hr (maximum the space can support) 56,000 BTU/hr (actual amount of
BTU/hr used)
The space in the above example is a conned 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:
a) Rework worksheet, adding the space of an adjoining room. If the extra space provides an
unconned space, remove door to adjoining room or add ventilation grills between rooms. See
“Ventilation Air From Inside Building,” page 9.
b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 9.
c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconned. If the actual BTU/hr
used is less than the maximum BTU/hr the space can support, the space is an unconned space.
You will need no additional fresh air ventilation.

9
PREPARING FOR INSTALLATION
Ventilation Air From Inside Building
This fresh air would come from adjoining
unconned space. When ventilating to an
adjoining unconned space, you must
provide two permanent openings: one
within 12 in. of the wall connecting
the two spaces (see options 1 and 2,
Fig. 4). You can also remove door into
adjoining room (see option 3, Fig. 4).
Follow the National Fuel Gas Code
NFPA 54/ANS Z223.1. Air for Combustion
and Ventilation for required size of
ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or duct. You must provide two
permanent openings: one within 12 in. of
the ceiling and one within 12 in. of the oor.
Connect these items directly to the outdoors
or spaces open to the outdoors. These
spaces include attics and crawl spaces.
Follow the National Fuel Gas Code NFPA
54/ANS Z223.1. Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated
air entering the attic will activate the power
vent. Rework worksheet, adding the space
of the adjoining unconned space. The
combined spaces must have enough fresh
air to supply all appliances in both spaces.

INSTALLATION
CONNECTING TO GAS SUPPLY
WARNING: A qualied service technician must connect heater to gas supply. Follow all local
codes.
CAUTION: Never connect heater directly to the gas supply. This heater requires an external
regulator (not supplied). The external regulator between the gas supply and heater must be installed.
Gas supplier provides external regulator for natural gas.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known
as wellhead gas.
The installer must supply an external regulator for liquid propane. The external regulator is
provided by the gas supplier for natural gas. The external regulator will reduce incoming gas pres-
sure. You must reduce incoming gas pressure to between 11 and 14 in. of water column for propane
and between 6 and 14 in. of water column for natural gas. If you do not reduce incoming gas pres-
sure, heater regulator damage could occur. Install external regulator with the vent pointing down as
shown in Fig. 9. Pointing the vent down protects it from freezing rain or sleet.
* Purchase the optional equipment shutoff valve from your local Home Center store.
CAUTION: Use only new black iron or steel pipe. Internally tinned copper tubing
may be used in certain areas. Check your local codes. Use pipe of ½ in. diameter
or greater to allow proper volume gas to heater. If pipe is too small, loss of pressure
will occur. Installation must include an equipment shutoff valve, union, and plugged
1/8-in. NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must
be upstream from heater (See Fig. 10).
IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment
shutoff valve is for turning on or shutting off the gas to the appliance. 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: Use pipe joint sealant that is resistant to gas (PROPANE or NG). We
recommend that you install a sediment trap in a supply line as shown in Fig. 10.
Locate sediment trap where it is within reach for cleaning and not likely to freeze.
Install in the piping system between fuel supply and heater.A sediment trap traps
moisture and contaminants. This keeps them from going into heater controls. If
sediment trap is not installed or is installed incorrectly, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when
connecting into gas piping and/or ttings. NG Models: 6 in. and 14 in. W.C. Gas
supplier provides external regulator for natural gas.

WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts
specically approved with this heater may result in property damage or personal injury.
CAUTION: After installation and periodically thereafter, check to ensure that no yellow ame comes in
contact with any log. With the heater set to High, check to see if yellow ames contact any log. If so,
reposition logs according to the log installation instructions in this manual. Yellow ames contacting
logs will create soot.
It is very important to install the logs
exactly as instructed. Do not modify logs.
Use only logs supplied with heater.
Each log is marked with a number.
this number will help you identify the logs
when installing.

INSTALLATION
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all
leaks immediately.
WARNING: Never use an open ame to check for a leak. Apply a mixture of liquid soap and water
to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )
1. Disconnect heater with its appliance main gas valve (control valve) and equipment shutoff valve
from gas supply piping system. Pressures in excess of 1/2 PSIG will damage heater regulator.
2. Cap off open end of gas pipe where equipment shutoff valve was connected.
3. Pressurize supply piping system by either using compressed air or opening gas supply tank valve.
4. Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. If
bubbles form, there may be a leak.
5. Correct all leaks immediately.
6. Reconnect heater and equipment shutoff valve to gas supply. Check reconnected ttings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (See Fig. 12).
2. Pressure supply piping system by either using compressed air or opening gas supply tank valve.
3. Check all joints from gas meter to equipment shutoff valve (See Fig.13).Apply mixture of liquid
soap and water to gas joints. If bubbles form, there may be a leak.
4. Correct all leaks immediately.
Pressure Testing Heater Gas Connections
1. Open equipment shutoff valve (See Fig. 12).
2. Open gas supply tank valve.
3. Make sure control knob of heater is in the OFF position.
4. Check all joints from equipment shutoff valve to control valve
(See Fig. 13). Apply mixture of liquid soap and water to gas joints.
If bubbles form, there may be a leak.
5. Light heater (see Operation, page 19-20).
Check all other internal joints for leaks.

OPERATION
FOR YOUR SAFETY
READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly, a re or explosion may
result causing property damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted by the electronic ignitor. When lighting the pilot,
follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the oor
because some gas is heavier than air and will settle on the oor.
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 re department
C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not
push in or turn by hand, don’t try to repair it, call a qualied service technician. Forced or attempted
repair may result in re or explosion.
D. Do not use this appliance if any part has been under water. Immediately call a qualied service
technician to inspect the appliance and to replace any part of the control system and any gas control
which has been under water.
E. Any safety screen or guard removed for servicing an appliance must be replaced prior to operating
the heater.

TO TURN OFF GAS TO APPLIANCE
1. (Select units) Open the lower access panel located under the heater screen.
2. Turn control knob clockwise to the “OFF” position.
3. (Select units) Close lower access panel.
INSPECTING BURNERS
Check pilot ame pattern and burner ame patterns often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot ame pattern. Figure 21 shows an incorrect pilot ame pattern. The
incorrect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool. When
the thermocouple cools, the heater will shut down.
If pilot ame pattern is incorrect, as shown in Figure 21.
• turn heater off (see To Turn Off Gas to Appliance, page 20.
• see Troubleshooting, page 23-25.
Note: The pilot ame on natural gas units will have a slight curve, but ame should be blue and have
no yellow or orange color.
WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon
monoxide. If burner ame pattern shows yellow tipping, follow instructions at bottom of this
page.
WARNING: Do not allow fans to blow directly into the heater. Avoid any drafts that alter burner
ame patterns.
WARNING: Do not use a blower insert, heat exchanger insert or other accessory not approved for
use with this heater.
Notice: Do not mistake orange ames with yellow tipping. Dirt or other ne particles enter the heater
and burn causing brief patches of orange ame.
