Venting
1. Locate the area(s) for mounting the hot air vent(s).
Note – Vents should be located so the heat will blow out in a desirable direction and allow easy access for
adjustments. They should be in area(s) that are protected from gear or persons damaging them.
2. Drill or cut the proper size hole to match the vents that you are using
Heater Craft vents:
• H-504 Directional Euro Vent uses a 3" hole saw
• H-506 Directional louvered Vent uses a 4 1/4" hole saw.
3. Mark the location of the mounting holes and pre-drill.
4. Install the vents ion place and attach the vent hose to them. Secure the vent hose with a plastic tie or
hose clamp.
5. Route the vent hose to the heater unit.
Note – Vent hoses should be routed to keep from being damaged.
6. Cut the vent hose to length, attach with a plastic tie or hose clamp, and secure in place.
Note – Vent hoses should be kept short as possible for greater heating efficiency.
