Forced Air Propane Heater FAQs

Why doesn't my heater come with a hose and/or regulator?

Your heater may not include a hose and/or regulator because it is not required for the product to function. Or there may be multiple options available in regards to the length of the hose, what length you need, etc.

What does the heating area square feet mean?

Square footage is the length of an area times the width of an area. Knowing the square footage of an area allows you to estimate the amount of BTUs necessary to heat the area most effectively. A generally accepted formula is: Square Footage x 40 = required BTUs. This is just a starting point. Ceiling height, building layout, and level of insulation will also factor into your BTU needs.

The motor starts on my heater but no heat comes out?

Check to see that your propane supply tank is turned on. Listen for the sound of the spark igniter, it should make a fast ticking sound, if it isn't you will need to call technical support for some additional trouble shooting help.

Why does my heater only run for a few minutes and than the shuts off?

You need to have the correct sized tank for the heater you are using. For every 50,000 Btu output you need a minimum of a 20 to 40 pound LP tank. In below freezing weather you may need to double the size of your propane source to maintain sufficient volume of flow for correct heater operation.

My heater has started giving off a bad smell?

There are different types of chemicals that, when drawn into the heater during its burning will react with the propane and make some disagreeable odors. The propane supplier may have added more of the orderizor to propane. First try the heater in a different area where no chemicals are used to see if the smell goes away and also try a different propane tank.

Why does my heater not spark?

Usually the igniter itself needs cleaned with steel wool and readjusted. The igniter should be a 1/4in away form the orifice assembly. If this does not fix the issue, then make sure there is power going to the assmbly. If so then the igniter is possibly bad or the board is bad. Please contect Technical Service or enter your serial number below at the base of the page to utilize the Interactive Schematic.

Is this heater indoor safe?

These heaters are outdoor only heater though they may be used in a garage setting or construction setting with proper ventilation. Standard ventilation is 1 square inch per 1000 BTUs. These heaters only have a thermocouple and high limit sensor but no ODS (Oxygen Depletion Sensor) so there is no way for the heater to know if its operating at dangerous O2 levels.
