Heater Installation
1. Locate the area(s) for mounting the hot air vents.
Note – Vents should be located so the heat will blow out in a desirable direction and allow easy access for
adjustments. Install them in areas that are protected from damage from gear or persons.
2. Drill or cut the proper size hole to match the vents that you are using.
Heater Craft Vents:
H-504, Directional Euro Vent – use 3" hole saw.
H-506, Directional Louvered Vent – use 4 1/4" hole saw.
H-509, Hot Tube Extendible Vent – use 4" hole saw.
Grilled /surface mount units:
4H series, cut out a 6 3/4" x 16" rectangle.
5H series, cut out a 6 3/4" x 9 3/4" rectangle.
8H series, cut out a 6 1/2" x 8 3/4" rectangle.
9H series, cut out a 4" x 8 5/8" rectangle.
3. mark the location of the mounting holes and pre-drill.
4. Mount the heater unit in the area chosen with the heater core in a horizontal position when possible.
Note – It may be easier to make the hose and wiring connections before mounting the heater unit.
5. Cut the water/coolant hoses to length, attach them with hose clamps, and secure in place.
Note – Fasten the hose clamps near the end of the hose to prevent the hose end from "mushrooming" and
to prevent coolant leakage.
Connect the hoses to either barb on the heater core.
6. Install the vents in place and attach the vent hose. Secure the vent hose with a plastic wire tie or hose
clamp.
7. Route the vent hoses to the heater unit.
Note – Route the vent hose in a way that prevents damage from gear or persons.
8. Cut the vent hose to length, attach with plastic wire tie or hose clamp and secure in place.
