How to Identify Your Model
The model name is printed on the label on the heater body. If the unit is already installed and the label is hard to reach, these differences will tell you which manual you need:
- Diesel or gasoline air heater — burns fuel and blows hot air into the cabin, with an exhaust pipe and a fuel line. Apollo-V1 is the 2.5 kW model, Apollo-V2 the 5 kW. Apollo-G1 is the gasoline version and draws from the vehicle’s own petrol tank.
- Engine block heater — plugs into mains power (110 V or 230 V) and warms the engine coolant before starting. Titan-P1 through P6 and B1.
- UTV cab heater — no fuel and no mains plug. It connects to the engine’s coolant hoses and blows cab heat through two round vents, with a 3-speed blower knob and a heat knob.
- Fuel heaters — Zeus-F3 fits on the fuel pickup inside the tank; Zeus-F1 is a silicone band that clamps around the fuel filter. Both prevent diesel from gelling in cold weather; neither heats the cabin.

Before You Install Any Heater
Two points come up across every product line, and they cause most of the support requests we receive:
- Bleed the air out of any coolant-fed system. Trapped air is the number-one cause of “installed correctly, no heat” on engine block heaters, cab heaters and water heaters alike. It is not a fault, and it usually takes more than one heat-and-cool cycle to clear.
- Work on a cold engine. Coolant above 180 °F (82 °C) is under pressure and causes serious burns. Never open a radiator cap, reservoir or coolant hose on a warm engine.
Model-specific safety warnings are in each manual. Read the safety section before starting the installation, not after.
