Unvented Liquid Propane Fired Room Heater

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, below.

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

3

 

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 (4.8 m

3

 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 fur-

nished with doors, are considered a part of the uncon-

fined space.

*Adjoining rooms are communication only if there 

are doorless passageways or ventilation grills be-

tween them.

Use this method to determine if you have a confined or 

unconfined space.

Note: the space includes the room in which you 

install heater plus any adjoining rooms with door-

less passageways or ventilation grills between the 

rooms.

1. Find the volume of the space by multiplying room 

length x width x height.

Example: Space size 18ft (length) x 18ft. (width) x 8ft.  

 

(height) = 2592

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 cubic feet to deter-

mine the maximum Btu/hr the space can support.

Example:  2592 cu.ft. (volume of space) / 50 cu.ft. =  

 

51.8 or 51,800 (maximum Btu/hr the space  

 

can support)

 WARNING: If the area in which the heater may be 

operated is smaller than defined as an unconfined 

space or if the building is of unusually tight con-

struction, provide adequate combustion and ventila-

tion air by the methods described in the National 

Fuel Gas Code, NFPA 54/ ANSI Z223.1, Section 

5.3 or applicable local codes. 

3. Add the Btu/hr of all the fuel-burning appliances 

in the space such as, Vent–free heater, Gas water 

This heater has a pilot with an Oxygen Depletion Sen-

sor (ODS) safety shut off system. The ODS/pilot shuts 

off the heater if there is not enough fresh air.

PIEZO: BF10LP/ IR10LP – The heater is equipped with 

a piezo manual ignitor. This system requires no match-

es, batteries, or other source to light heater.

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.

1.  Remove heater from carton.
2.  Remove all protective packaging applied to 

heater for shipment.

3.  Check heater for any shipping damage. If 

heater is damaged, promptly inform dealer 

where you bought heater.

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
