Fitting the pellet hoses
1. Trim the hoses to the required length.
Allow an extra 2 in. (50 mm) for connection of the
ground wire at the end of each hose.
Expose the ground wire by approx. 2 in. (50 mm) at each
hose end. Bend the ground wire inwards into the hose.
2. Make a bare metal connection at all connectors
(including that on the room discharge).
3. Route the pellet supply and return air hoses through
the apertures in the back panel. Push all hoses with
ground wire over the bare metal part of the
connectors.
4. Secure the hoses to the connectors using hose clamps.
5. Secure hoses to the wall using wall mounting brackets
no more than 40 in. (1000 mm) apart.
Note: We recommend fitting the clips of the hoses
with anti-vibration anchors.
