Below are some FAQ’s that will aid you in the use
of your ground thaw units. As we discover more FAQ’s we will
communicate them to you.
FAQ #1. The plunger on the thermocouple won’t
push down to light the unit. What has happened?
Answer #1. As the ground thaw unit cools after use,
the warm, moist air created from using the ground thaw unit has condensed and
frozen on the inside of the thermocouple plunger guide/housing. To thaw the
thermocouple, simply hold your bare fingers on the brass surrounding the base
of the plunger for 15-20 seconds. The heat transferred from your fingers
will thaw the frozen moisture, allowing you to depress the plunger and light
the unit. Do not apply an open flame to the thermocouple plunder and
base, as you may damage some delicate internal parts of the unit, defeating
the safety features and causing premature failure
FAQ #2. My unit lights and appears to be working
properly. When I check the unit the next day I have found the unit has gone
out sometime during the thaw job. What can cause this?
Answer #2. The ground thaw unit is vented around
the infrared-heating unit. This supplies the oxygen needed for the
burner. If you seal the ground thaw unit too tightly with insulation or
sand and operate the burner on the "high" setting, the unit may not
get enough oxygen from the vent – causing the unit to go out. When you
place the unit on the ground, we recommend that you use sand or insulation
around the unit to seal the air gaps for a better thaw– but PLEASE leave a
small air opening (1/2" high and about 1" long) between the ground
and the unit somewhere on the opposing end of the infra-red heater. This
will allow a proper air exchange, and will not effect the thawing performance.
