Heat Wagon 2730C, Installation And Maintenance Manual

Page: 8 / 16

COMMON INSTALLATION AND OPERATIONAL PROBLEMS
1) LOW VOLTAGE AT THE HEATER
This is one of the most common problems and is usually the result of the supply cord having
too small a wire gauge for its length, or low voltage at the power source. Low voltage results in
the motor overheating, burnt relay contacts, or a relay that will not make contact. Check
voltmeter on heater before start-up.
2) SUPPLY LINE TOO SMALL
Minimum Size: 1/2” for LP, 3/4” for Natural Gas.
3) INSUFFICIENT VAPORIZATION AT SUPPLY
Normally caused by undersized supply tank.
4) IMPROPER GAS SUPPLY PRESSURE
Usually a result of propane supply pressure being too high because of improper or lack of
regulation or too low of natural gas pressure at meter.
5) DIRTY GAS SUPPLY
Dirty gas can cause strainers to plug or form a build-up in the burner orifice.
6) LACK OF PREVENTIVE MAINTENANCE
Heaters must be cleaned as required, especially when used in a dirty environment.
7) IMPROPER SUPPLY OF FRESH AIR
It is strongly recommended that the intake air of the heater be taken from outside the enclosed
area. This provides a slight pressurization and prevents any problems associated with
recirculation of products of combustion.
