1. Attach Vertical Guide Bracket (VGB) to the Top of the rear air supply chamber.
a. Centre the VGB around the control rod opening as per diagram and position the two vertical fi ngers of
the VGB so the bend in these fi ngers are fl ush with the back side of the shutter plate.
b. Locate VGB on screws inserted in the predrilled holes of the rear air supply chamber, as per diagrams.
DO NOT TIGHTEN SCREWS SO BRACKET CAN BE ADJUSTED.
c. With shutter plate pushed towards the front of the furnace in the air damper assembly slot, and the base
of the VGB held fi rmly down on the top of the air supply chamber, position the bend in the vertical fi ngers
so there is a 0" to 1/32" gap between the back of the shutter plate and the bend in the vertical fi ngers.
THE FINGERS MUST NOT EXERT ANY FORWARD FORCE ON THE SHUTTER PLATE WITH THE
MOUNTING SCREWS TIGHTENED. THE SHUTTER PLATE MUST SLIDE UP AND DOWN FREELY IN
THE SLOT, AND SHOULD READILY FALL (GRAVITY ONLY) INTO THE SLOT IF RAISED BY HAND
2" (51mm) AND RELEASED. IF ANY TENSION EXISTS BETWEEN VGB AND SHUTTER PLATE, THE
FRICTION MAY PREVENT THE SHUTTER PLATE FROM FALLING, CAUSING THE FURNACE TO
OVER FIRE.
