SAFETY
Propane Gas: Propane gas is odorless. An
odor-making agent is added to propane gas.
The odor helps you detect a propane gas
leak. However, the odor added to propane
gas may fade. Propane gas may be present
even though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this heater.
1. Install and use heater with care. Follow all
local ordinances and codes. In the absence
of local ordinances and codes, refer to
the Standard for Storage and Handling of
Liqueed Petroleum Gas, ANSI/NFPA 58
Natural Gas Installation Code, CAN/CGA
B149.2. This instructs on the safe storage
and handling of propane gases.
2. State of Massachusetts: The installation
must be made by a licensed plumber or
gas tter in the Commonwealth of Mas-
sachusetts.
3. Use only propane gas set up for vapor
withdrawal.
4. Provide adequate ventilation. Before us-
ing heater, provide at least a 2.5 square
foot (0.232 m2) (80,000 Btu/Hr heaters) or
6.0 square foot (0.557 m2) (200,000 Btu/
Hr heaters) opening of fresh, outside air.

thinner and other ammable vapors and
liquids. Dust is combust ble. Do not use

advise you about these. The primary purpose
of construction heaters is to provide tempo-
rary heating of buildings under construction,
alteration or repair. Properly used, the heater
provides safe economical heating. Products
of combustion are vented into the area being
heated.
