STEP #2
○
Once the secondary tube has been pushed completely to the right and the key has engaged the keyway,
insert a hitch pin into the left most clearance hole of the secondary tube.
STEP #3
○
Carefully pivot the compressed vermiculite baffl es up onto the rear secondary air tubes as illustrated. En-
sure that the top baffl es are pushed all the way to the rear of the fi rebox overlapping the rear bricks, leav-
ing a minimum 2.75" (70mm) (CHMF150) / 4.75" (121mm) (CHMF200) gap along the front. This will allow
the fl ue gases to escape the fi rebox. Spread the baffl es tight to each side to ensure there are not gaps, as
illustrated.
