Low Voltage
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.
Low voltage results in the motor overheat-
ing, burnt relay contacts, or a relay that will
not make contact.
Supply Line Too Small
Insufficient Vaporization At Supply
Normally caused by too small size of supply
tank.
Improper Gas Supply Pressure
Usually a result of supply pressure being
too high because of improper or lack of
regulation.
Common Installation And Operational Problems
Dirty Gas Supply
Dirty gas can cause strainers to plug or
form a build-up in the burner orifice.
Lack Of Preventative Maintenance
Heaters must be cleaned as required, espe-
cially when used in a dirty environment.
Improper Supply Of Fresh Air
It is normally recommended that the intake
air of the heater be taken from outside the
enclosed area. This provides a slight pres-
surization and
prevents any problems associat-
ed with recirculation.
Bypassing of Defective
Components
This is a potentially dangerous problem
which saves short term expense at the risk
of a large future cost. Any heaters found
in this condition should be removed from
service immediately
Improper Enclosures
When heaters are installed partially to the
outside for fresh air intake, strict adherence
must be made to the minimum clearance to
combustibles given on the instruction plate.
Wood framing around a heater is a hazard
and should no be used.
On-site Safety Problems
Supplying Liquid Propane To Heater
This heater is not intended to burn liquid
propane. To minimize the damage, shut off
the gas supply and let the heater run until all
of the liquid in the lines has been burnt.
