When used without adequate combustion and ventilation heater air may give off carbon monoxide.
Check your local building codes for the proper method of installation. In the absence of local codes, this heater
installation must conform with American National Standard (National Fuel Gas Code) ANSI Z223.1.
Available from the American National Standards Institute, Inc.,
1430 Broadway, New York, NY 10018, or from the National Fire
Protection Association, Batterymarch Park, Quincy, MA 02269.
All correspondence should refer to Model No., Serial No., and type of gas.
WARNING: Electrical Grounding Instructions
This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong receptacle.
This appliance may be installed in an aftermarket manufactured (mobile) home where not prohibited by state or
local code.
Aftermarket = completion of sale, not for purpose of resale from manufacturer.
This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided
for adequate combustion and ventilation air.
The National Fuel Gas Code ANSI Z223.1 defines a confined space as a space whose volume is less than 50 cubic
feet per 1,000 Btu per hour (4.8m3 per kW) of the 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 (4.8m3 per kW)
of the aggregate input rating of all appliances installed in that space.
Rooms communicating directly with the space in which the appliances are installed, through openings not furnished
with doors, are considered a part of the unconfined space.
The following formula can be used to determine the
maximum heater rating per the definition of unconfined
space:
BTU/HR = (L1 +L2)Ft X (W)Ft X (H) Ft X 1000
50
Consider two connecting rooms with an open area
between, with the following dimensions:
BTU/HR = (15 1/2+12) X (12) X (8) X 1000
50
= 52800 BTU/HR
If there is a door between the two rooms that can be
closed the calculation must be based only on the room
with the heater.
BTU/HR = (15 1/2) X (12) X (8) X 1000
50
= 29760 BTU/HR
WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if
the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the
methods described in the National Fuel Gas Code, ANSI Z223.1, Section 5.3 or applicable local codes.

Model RCE-229A 800-621-94199
Unusually tight construction is defined as construction where:
a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a
rating of 1 perm (6X10-11kg per pa-sec-m2) or less with openings gasketed or sealed, and
b) Weather stripping has been added on openable windows and doors, and
c) Caulking or sealants are applied to areas such as joints around window and door frames, between sole
plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing,
electrical, and gas lines, and at other openings.

Clean air filter at least once a week. Do not wait for filter
warning lamp to come on before cleaning filter. Do not use
the heater with the filter warning lamp on, this may cause it
