Introduction
Thank you for purchasing our PHP-40A heater kit.
The PHP-40A heater is designed to provide cabin heating for larger truck sleepers,
off-highway equipment, RVs and boats by using on-board diesel fuel and battery systems.
Operation is simple and the heater provides a safe and reliable alternative to engine idling or
need for electrical plug ins.
Please take a moment to familiarize yourself with this manual, safety warnings and heater
requirements before installing or operating your heater.
