sensing bulb. This results in the greatest heater comfort 

and may result in lower bills.
These heaters also include an electrical blower. The 

blower switch has three positions: MANUAL, OFF and 

AUTO. In AUTO, the blower will turn on and off as the 

heater cycles on and off. On MANUAL, the blower will run 

continuously. To turn blower off, use the OFF position.

Install and use heater with care. 
Installation must conform to local codes or in the ab-

sences of local codes, use the latest edition of National 

Fuel Gas Code ANSI Z223.1/NFPA 54.

WARNING: This heater shall not be installed in a 

confined space or unusually tight construction un-

less provisions are provided for adequate combus-

tion and ventilation air. Read the following instruc-

tions to insure proper fresh air for this and other 

fuel-burning appliances in your home. 

The following are excerpts from National Fuel Gas 

bustion and Ventilation. All spaces in homes fall into 

one of the three following ventilation classifications:

1.  Unusually Tight Construction
2.  Unconfined Space
3.  Confined Space

This heater must not be installed in a confined space or 

unusually tight construction unless provisions are pro-

vided for adequate combustion and ventilation air. The 

information on pages 3 through 5 will help you classify 

your space and provide adequate ventilation.

If your home meets all of the three following criteria you 

must provide additional fresh air. See Ventilation Air 

from Outdoors, page 5.
Unusually tight construction is defined as construction 

where:
a. Walls and ceilings exposed to the outside atmo-

sphere have a continuous water vapor retarder with 

a rating of one perm (6 x 10

-11

 kg per pa-sec-m

2

) or 

less with openings gasketed or sealed and

b. Whether stripping has been added on openable win-

dows and doors, and 

c.  Caulking or sealants are applied to areas such as 

joints around windows and door frames, between 

wall-ceiling joints, between wall panels, at penetra-

tions for plumbing, electrical, and gas lines, and at 

other openings. 

If you home does not meet all of the three criteria 

above, see Determing the Type of Heater Location 

Space, page 4.

The National Fuel Gas Code, NFPA 54/ ANSI Z223.1 

defines a confined space as a space whose volume is 

less than 50 cubic feet per 1,000 Btu per hour (4.8 m

per kW) of the aggregate input rating of all appliances
