TO START HEATER
1.
Follow all installation, ventilation and safety information.
2.
Locate heater on stable and level surface. Make sure strong
drafts do not blow into front or rear of heater.
3.
Make sure the control knob is in the OFF position.
4.
Plug power cord of heater into a three-prong, grounded extension
cord. Extension cord must be at least six feet long, UL/CSA listed,
and of a proper size.
Extension Cord Size Requirement
Up to 100 feet long, use 16 AWG rated cord.
101 to 200 feet long, use 14 AWG rated cord.
5.
Plug extension cord into a 120 volt/60 hertz, 3-hole, grounded
outlet. Motor will start. Fan will turn, forcing air out front of heater.
6.
Open propane supply valve on propane tank(s) slowly.
Note:
If
not opened slowly, excess-flow check valve on propane tank
will stop gas flow. You may hear a click from the excess-flow
check valve closing. If this happens, reset the excess-flow check
valve by closing propane supply valve and open again slowly.
7.
Press and hold in control knob. Turn counterclockwise to the
LOW position. Heater should ignite within a few seconds.
Note:
If heater fails to ignite, hose may have air in it. If so,
keep control knob pressed and wait 20 seconds. Release auto-
matic control valve button and wait 20 seconds for unburned
fuel to exit heater. Repeat step 7.
8.
After heater ignites, wait 30 seconds. This activates the auto-
matic control system. Release the control knob.
9.
When burner remains lit, set heater at the desired heat level by
turning the control valve counterclockwise. If burner goes out,
turn off gas. Turn control knob fully clockwise to the lowest
position. Check fuel supply. If adequate fuel is available, re-
start heater beginning at step 1.
