4.0 IMPORTANT SAFETY INFORMATION (continued)
• Children and adults should be alerted to the hazard of high surface
temperature and should stay away to avoid burns or clothing ignition.
• Young children should be carefully supervised when they are in the
same room with the heater.
• Do not place clothing or other flammable material on or near the
heater.
• Any safety screen or guard removed for servicing the heater must be
replaced prior to operating the heater.
• Installation and repair should be done by a qualified service person.
The heater should be inspected before use and at least annually by a
professional service person. More frequent cleaning may be required
due to excessive lint from carpeting, bedding material, etc. It is
important that control compartments, burners and circulating air
passageways of the heater be kept clean.
• Allow the heater to cool before servicing. Always shut off the gas to
the heater while performing service work.
• The installation must conform with local codes or, in the absence of
local codes with the National Fuel Gas Code, ANSI Z223.1.
• The heater and its individual shut-off valve must be disconnected
from the gas supply piping system while performing any tests of the
gas supply piping system at pressures in excess of 1/2 psig.
• The heater must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to or
less than 1/2 psig.
• Keep heater area clear and free from combustible materials, gasoline
and other flammable vapors and liquids.
• Do not use this heater if any part has been under water. Immediately
call a qualified service technician to inspect the room heater and to
replace any part of the control system and any gas control which has
been under water.
• Input ratings are shown in BTU per hour and are for elevations up to
4,800 feet. Do not install this heater at an elevation above 4,800 feet if
the gas supply has not been derated for that elevation. Consult your
local gas supplier. (For operation at elevations above 4,800 feet,
equipment ratings shall be reduced at the rate of 4 percent for each
1,000 feet above sea level before selecting appropriately sized
equipment.)
• Ensure that the heater is clean when operating. Excessive dust
accumulation on the burner will increase the amount of carbon
monoxide formation and could lead to carbon monoxide poisoning
and/or death.
• This appliance is intended for supplemental heating

5.0 CODES

Adhere to all local codes or in their absence the latest edition of The
National Fuel Gas Code ANSI Z223.1 or NFPA54 which can be obtained
from The American National Standards Institute, Inc. (1430 Broadway, New
York, NY, 10018) or National Fire Protection Association, Inc.
(Batterymarch Park, Quincy, MA, 02269).
Seller of unvented propane or natural gas fired supplemental room heaters
shall provide to each purchaser a copy of 527 CMR 30 upon sale of the
unit.
This Focal Point Unvented Gas Room Heater is certified by OMNI-Test
Laboratories, Inc to ANSI Z21.11.2-2004b standard.

6.0 COMBUSTION AND VENTILATION AIR

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/NFPA 54 defines a confined
space as a space whose volume is less than 50 ft
m per kW) of the aggregate input rating of all appliances installed in that
3
space and an unconfined space as a space whose volume is not less than
50 ft 3 per 1,000 BTU/Hr (4.8 m
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.
Unusually tight construction is defined as construction where:
a. wall and ceilings exposed to the outside atmosphere have a continuous
water vapor retarder with a rating of one perm or less with openings
gasketed or sealed, and
b. weather stripping has been added on operable 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 wallceiling joints,
between wall panels, at penetrations for plumbing, electrical, and gas lines,
and at other openings.
Use the following equations to determine if you have a confined or
unconfined space.
1.
Determine the volume of space — ft
Length x Width x Height = _____ ft
(Include adjoining rooms with doorless passageways or ventilation
grills between rooms.)
Example: 24' (L) x 16' (W) x 8' (H) = 3072 ft
2. Divide the volume of space by 50 ft
BTU/Hr the space can support.
______ (volume of space – ft
(Maximum BTU/Hr the space can support)
Example: 3072 ft 3 / 50 ft 3 = 61.44
or 61,440 BTU/Hr the space can support.
3.
Add the BTU/Hr of all the fuel burning appliances in the space.

Gas appliance #2 + _______ BTU/Hr
Gas appliance #3 + _______ BTU/Hr
Example:
Vent-free heater #1
Vent-free heater #2
