FIREPLACE CLEARANCES (ZC)
The fireplace may be placed directly on a combustible floor,
against a combustible wall at marked clearances or on a
raised wooden platform.
If fireplace is to be installed on a raised wooden platform, the
platform must be a continuous level surface. The fireplace
must be secured in place so it cannot shift positions. The
nailing flanges on sides of firebox make securing it to
framing easy. They were designed to allow installation of
1/2" wallboard or plywood flush with face of fireplace.
Only header (see Figure 2) may rest on standoffs on top of
firebox.
When firebox is installed over carpeting, vinyl tile or
any combustible material other than wood flooring, it
must be installed on a metal or wood panel extending its full

PRODUCING ADEQUA TE AIR FOR
COMBUSTION AND VENTILATION
This section is for residential or manufactured (mobile) installation
“This heater shall not be installed in unusually tight construction unless provisions are adequate
for combustion and ventilation air.”
NOTE: This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by method in the National Fuel Gas Code, ANSIZ223.1/NFPA 54,International Fuel Gas Code, or applicable codes.
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines unusually tight construction or
unconfined space as a space whose volume is less than 50 cubic feet per 1,000 BTU per hour
(4.8m 3 per kw) of aggregate input rating of all appliances installed in that space and an
unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 BTU per
hour (4.8m 3 per kw) of aggregate input rating of all appliances installed in that space. Rooms
communicating directly with space in which appliances are installed, through openings not
furnished with doors, are considered a part of unconfined space.
“WARNING: IF THE AREA IN WHICH HEATER MAY BE OPERATED DOES NOT
MEET REQUIRED VOLUME FOR INDOOR COMBUSTION AIR, COMBUSTION
AND VENTILATION AIR SHALL BE PROVIDED BY ONE OF METHODS DESCRIBED IN NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54, INTERNA-TIONAL FUEL GAS CODE, OR APPLICABLE CODES.”
“WARNING: IF AREA IN WHICH HEATER MAY BE OPERATED IS SMALLER
THAN THAT DEFINED AS AN UNCONFINED SPACE OR IF BUILDING IS OF
UNUSUALLY TIGHT CONSTRUCTION, PROVIDE ADEQUATE AIR FOR
COMBUSTION AND VENTILATION BY ONE OF METHODS DESCRIBED IN
NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54 AIR FOR COMBUSTION AND
VENTILATION OR APPLICABLE LOCAL CODES.”
Unusually tight construction is defined as construction where:
a) Walls and ceilings exposed to outside atmosphere have a continuous water vapor retarder
with a rating of 1 perm (6 x 10
b) Weather stripping has been added on openable windows and doors.

DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
DETERMINE IF YOU HAVE UNUSUALLY TIGHT CONSTRICTION OR UNCONFINED SPACE
Use this worksheet to determine if you have confined or unconfined space.
SPACE: Includes the room in which you will install heater plus adjoining rooms with
doorless passageways or ventilation grills between rooms.
1. Determine the volume of space (length x width x height).
Length x Width x Height =_________cu.ft.(volume of space)
EXAMPLE: 20 ft.(Length) x 16 ft.(Width) x 8 ft.(ceiling Height)=
2560 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills or openings, add volume
of these rooms to total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the maximum BTU/Hr 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
51200 (maximum BTU/Hr space can support)
3. Add the BTU/Hr of all fuel burning appliances in space.
Vent-free heater _______________BTU/Hr
Gas water heater* _______________BTU/Hr
Gas furnace _______________BTU/Hr
Vented gas heater _______________BTU/Hr
Gas fireplace logs _______________BTU/Hr
Other gas appliances* + _______________BTU/Hr
Total = _______________BTU/Hr
Example: Gas water heater 40000 BTU/Hr
Vent-free heater + 18000 B
Total = 58000 BTU/Hr
*Does 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 actual amount of BTU/Hr
used.
____________BTU/Hr (maximum the space can support)
____________BTU/Hr (actual amount of BTU/Hr used)
Example: 51200 BTU/Hr (maximum the space can support)
58000 BTU/Hr (actual amount of BTU/Hr used)
The space in the above example is unusually tight construction space because 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:
TU/Hr
Page 12
Page 17
A. Rework worksheet, adding space of an adjoining room. If the extra space provides an
unconfined space, remove door to adjoining room or add ventilation grills between rooms. See
“Air For Combustion And Ventilation From Inside Building”, figure 6.
B. Vent room directly to outdoors. See “Air For Combustion And Ventilation From
Outdoors”, page 14.
C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes room unconfined.
If actual BTU/Hr used is less than maximum BTU/Hr space can support, space is an
unconfined space. You will need no additional fresh air ventilation.
WARNING:
YOU MUST PROVIDE ADDITIONAL VENTILATION AIR IN UNUSUALLY TIGHT
CONSTRUCTION
AIR FOR COMBUSTION AND VENTILA TION

THERMOSTAT CONTROL OPERATION
1. The thermostat control on this heater differs from standard thermostats. Standard
thermostats simply turn burner on and off. The thermostat used on this heater senses
room temperature and adjusts amount of gas flow to burner. This will increase or
decrease flame height. At times, room may exceed set temperature, which will cause
the burner to shut off. When room temperature drops below the thermostat setting,
burner will cycle itself on again. The control knob can be set to any level between
“LO” and “HI”.
NOTE: The thermostat sensing bulb measures temperature of air near heater
cabinet.This may not always agree with room temperature (depending on
housing construction, installation location, room size, open air temperatures,
etc.). Frequent use of your heater will allow you to determine your personal
comfort levels.
