H-45 TYPE I (SOLID FUEL) HEATER
Burning Off The Protective Film On The H-45 Type I (Solid Fuel) Heater Prior To Use
The metal surfaces of the H-45 heater body are shipped from the
manufacturer with a protective film that must be burned off prior to the
initial use of the heater in an enclosed area. Failure to do so could result
in inhaling harmful fumes.
1. To burn off the protective film, you need to set up and operate the H-45 Type I (Solid Fuel) Heater in
an open area outside of the tent. The following three sections of this work package describe
Preparing The H-45 Type I (Solid Fuel) Heater for Operation, Assembling The Stack For H-45
Type I (Solid Fuel) Heater Operation, and Starting The H-45 Type I (Solid Fuel) Heater.
All six stack pipe sections must be assembled, put securely in place on
the top heater shell flange, and tied down during the burnoff. Failure to
use all six sections will adversely affect heater performance, increase
soot buildup, and increase maintenance.
2. Once the heater is hot, you will see smoke coming off the metal surfaces as the protective film burns
off. Allow the heater to burn until no more smoke is observed.
3. Shut down the heater, allow it to cool, and move it inside the tent. See the following sections in this
work package: Shutting Down The H-45 Type I (Solid Fuel) Heater and Preparing The H-45 Type I
(Solid Fuel) Heater For Movement. Then repeat the instructions detailed in the sections listed in step
