Operating Instructions and Owner’s Manual

Mr. Heater | Gas-Fired Infra-Red Portable Heater

The bulk propane tank “on-off” valve should ALWAYS be
completely turned “OFF” when the heater is not in use.

When shutting off the heater, turn the regulator knob on the

heater to “OFF” (clockwise). (See Figure 4)

CAUTION: After turning unit off, heater will remain

extremely hot. Allow at least 15 minutes for cooling before
handling and storing. Detach heater from bulk tank before
handling and storage. REMEMBER – POL fitting is a left-hand
thread.

The chart assumes that the proper gas and gas pressure is available to the heater. The chart also assumes that the heater is used in
accordance with Mr. Heater installation and operating instructions.

If satisfactory results cannot be obtained after performing any of the above procedures,

Please call Mr. Heater’s Customer Care Center at 1-800-251-0001. Thank you.

HEATER STORAGE: Always remove the propane cylinder from
the heater when not in use. Always store propane cylinders in
a cool, well ventilated place away from any flame or heat and
in a location not used for habitation. DO NOT STORE PROPANE
TANK WITHIN 60 FT. OF OPEN FLAME OR HEAT.
