PORTABLE FORCED AIR HEATER

200,000 Btu/Hr

FUELS

Do not use heavy fuels such as No. 2 fuel oil
or No. 2 Diesel. Using heavy fuels will
result in:

• clogged fuel filter and nozzle

• carbon build up on spark plug

• the need of nontoxic anti-icer in fuel dur-

ing very cold weather

IMPORTANT:

Use a KEROSENE ONLY

storage container. Be sure storage container
is clean. Foreign matter such as rust, dirt, or
water will cause the flame-out control to
shut down heater. Foreign matter may also
require you to clean fuel system often.

These models are furnished with wheels and
a front handle. Some models are furnished
with a rear handle also. Wheels, handle(s),
and the mounting hardware are found in the
shipping carton.

Tools Needed

• Medium Phillips Screwdriver

• 3/8" Open or Adjustable Wrench

• Hammer

Slide axle through wheel support
frame. Install wheels on axle.

IMPORTANT:

When installing wheels,

point extended hub of wheels toward
wheel support frame (see Figure 2).

WARNING:Use only kerosene

or No. 1 fuel oil to avoid risk of fire
or explosion. Never use gasoline,
naphtha, paint thinners, alcohol,
or other highly flammable fuels.

VENTILATION

WARNING: Follow the mini-

mum fresh, outside air ventila-
tion requirements. If proper fresh,
outside air ventilation is not pro-
vided, carbon monoxide poison-
ing can occur. Provide proper
fresh, outside air ventilation be-
fore running heater.

Provide at least a three-square-foot opening
of fresh, outside air for each 100,000 Btu/Hr
rating. Provide extra fresh air if more heat-
ers are being used.

Example:

A 200,000 Btu/Hr heater re-

quires one of the following:

• a two-car garage door (16 feet wide open-

ing) raised five inches

• a single-car garage door (9 feet wide

opening) raised eight inches

• two windows (30 inches wide opening)

raised fifteen inches
