propane heater designed for heating cargo. These heaters have pilot light to preheat the
catalyst hen the heater is first lit but, once lit, the pilot light is shutoff and the heater
becomes flameless. The heater maintains the temperature of your cargo by s itching
bet een t o levels of heat output: a lo heat output and the full 18000 BTU/hr heat
output.
Your heater is one of t o models, either the CAT-700 or the CAT-900. Both models
share the same basic heater but differ in the number and size of the propane fuel tanks
they can carry. The CAT-700 stores a single 20lb propane bottle in the base hile the

components sho n belo in Illustration 2.
The CAT-700 has very similar components
except it lacks the tank selection and
