Operating Instructions and Owner’s Manual
Mr. Heater | Gas-Fired Infra-Red Portable Construction Heater
The minimum ambient temperature rating for this heater is 20
degrees F.
This heater incorporates a “Tip Over” switch which automatically
shuts off the burner in the event of tipping. Ensure that this
switch is in the vertical position and is secured with the screws
provided (see Fig. 4).
DO NOT operate this heater with the
LP-gas supply cylinder in any other than the upright
position.
LOCATION
Although this heater incorporates a “tip over” switch, the heater
and LP-Gas supply cylinder must be located on a hard, flat, level
surface to minimize the risk of accidental tipping. The LP Gas
supply cylinder should be adequately restrained to prevent
accidental tipping.
DO NOT OPERATE this heater with the
supply cylinder in any other than the upright position.
This appliance must be installed only in locations where the
potential for physical damage to the appliance (i.e., due to
physical contact) is reduced to a minimum.
The installer must inform the owner/operator of this appliance
that precautions must be taken to protect the appliance from
physical damage.
This appliance produces radiant heat. Therefore, it must be
located at least six feet away from any LP-Gas container and
must not be directed toward any LP-Gas container within 20 feet.
The heater must be installed in a location such that it will not be
exposed directly to water spray, rain, and/or dripping water.
Use of this heater in a draft/windy area may decrease its
efficiency. If possible, operate the unit in a draft free area or
turn the face of the heater away from the draft.
PIPING:

This model may be connected to a self-contained LP-Gas supply
system using the hose and regulator assembly supplied with the
appliance, OR, it may be connected to a permanently installed
LP-Gas supply system.
If connected to a self-contained LP-Gas supply system, the hose
assembly must be inspected prior to each use of the heater. If it
