B) Position the MOU2,_T1NG GASKET (3) between the flat surface of the UNIVERSAL MOU2qT1NG
FLANGE (10) and the appliance. Line up the holes in the UNIVERSAL MOUNT1NG FLANGE with the
STUDS (4) on the appliance mounting plate and securely bolt the UNIVERSAL MOU2,_T1NG FLANGE to
the plate.
C) Secure the two semi-flanges of the ADJUSTABLE COLLAR (9) to the AIR TUBE using the two long
BOLTS (6). Be sure that the ADJUSTABLE COLLAR (9) is properly positioned so the outside edge of the
END CONE will be at least */4inch (6.51ran) back from the inside wall of the refractory of the combustion
chamber (see dimension B above). The measured length (A) is to include MOU_NT1NG GASKET and
FLANGE, if used.
D) The bumer may now be attached to the heating unit by insetting the AIR TUBE through the BUNNER
ACCESS HOLE (8) and into the appliance, making sure the BOLTS (1) line up with the two HOLES (5) in
the ADJUSTABLE COLLAR (9). Secure the burner in place using two NUTS (7).
A visual verification of the air tube insertion into the combustion chamber of the heating unit is suggested.
Dimension B should be at least */4"(see drawing).
NOTE: A suggested method for creating mounting bolt holes in the mounting gasket: Hold the gasket against
the appliance mounting bolts using the mounting flange for proper positioning. Lightly tap the flange with a
halraner to form the holes.
METHOD 2 - SEMI-FLANGE COLLAR
A) Follow item C from METHOD 1.
B) Align the air tube and attached adjustable collar so air tube is centered in the bumer access hole of the
boiler/furnace unit. Mark the center of the two holes in the ADJUSTABLE COLLAR on to the front plate of
the heating unit. Then drill */4inch (6.51run) holes through the front plate of the unit, using marks as a guide.
C) Install two short BOLTS (1) through the front plate of the heating unit from the inside, and secure on the
outside using the two special CHROME NUTS (2).
D) Follow item D from METHOD 1.
