With the heater mounted, slip the heater hoses onto the nipples of the
core and tighten all the hose clamps. Check all hose and fittings for
security and chafing.
29.
Connect wires to fan and route them to the switch and power source.
30.
To keep the hoses out of the rudder pedals, use a 1" cushioned clamp
bolted to the firewall. Test operate the pedals to assure tangle free
movement. After the hoses are clamped to the firewall, install the Hose
Covers. The cover of the hose that is clamped to the firewall will need to
be cut with a hot knife to fit around the clamp, or remove the cushion off
the clamp to allow clearance. Tie the hoses together with Plastic Ties.
IMPORTANT: Double check to be sure there is no interference with
Rudder Pedals.
31.
After final engine install, check for coolant leaks and proper operation
during engine test run.
32.
The heater should produce noticeable heat within a few minutes of starting
the engine. Depending on how well your cabin is sealed, and the outside
air temperature, the heater should be able to keep the cabin warm enough
for extended flying on winter days, or at altitude. Do not expect the heater
to keep up if you have many air leaks in your cabin, or if it is extremely
cold (below 20 degrees F.).
