installation instructions (continued)
On solid wall, when using wall studs for attachment of wall mounting
bracket, fasten wall mounting bracket to wall studs with (2) #10 x
1 1/2" (38mm) screws provided and fasten (2) additional #10 x 1
1/2" (38mm) screws provided through the wall mounting bracket
and into the solid wall.
On sheet rock, when using wall studs for attachment of wall mounting
bracket, fasten wall mounting bracket to wall studs with (2) #10
x 1 1/2" (38mm) screws provided and by using wall opening for
access, fasten 2 additional #10 x 1 1/2" (38mm) screws and (2)
Tinnerman nuts provided through the wall mounting bracket and
into the sheet rock.
attaching Furnace to Wall Mounting Bracket
Hang furnace on wall mounting bracket by aligning (2) tabs on wall
mounting bracket with (2) slots located on inner casing top.
The inner casing bottom is to be fastened to the wall. On solid wall,
fasten inner casing bottom with (2) #10 x 1 1/2" (38mm) screws
provided. On sheet rock wall, fasten inner casing bottom with (2)
toggle bolts provided.
cutting Vent tubes
This is the most important part of the installation. With the furnace
installed on wall the 6" (152mm) diameter air inlet tube and the 4"
(102mm) diameter flue outlet tube are to be marked and cut using
the following procedure.
1. Attach 6" (152mm) diameter air inlet tube onto the collar of air
drop assembly. Be sure 6" (152mm) diameter air inlet tube is
placed as far as possible onto the collar of the air drop assembly.
Mark the 6" (152mm) diameter air inlet tube 1/2" (13mm) beyond
the outside wall. Remove 6" (152mm) diameter air inlet tube
from collar of air drop assembly.
2. Attach 4" (102mm) diameter flue outlet tube onto flue outlet
collar on combustion chamber. Be sure 4" (102mm) diameter
flue outlet tube is placed as far as possible onto the collar of
flue outlet. Mark the 4" (102mm) diameter flue outlet tube 2 1/2"
(64mm) beyond the outside wall. Remove 4" (102mm) diameter
flue outlet tube from collar of flue outlet on combustion chamber.
3. Mark or wrap tape completely around the tubes at the marked
points to help in making a true cut. Do not crimp or enlarge
tubes.
installing Vent assembly
1. Place caulking (not provided) beneath the edge of the outside
mounting plate. Use additional caulking to correct uneven wall
surface, such as clapboard.
2. Attach 6" (152mm) diameter air inlet tube onto the collar of air
drop assembly. Attach caulked, outside mounting plate into
the 6" (152mm) diameter air inlet tube. Position the outside
mounting plate so that 6" (152mm) diameter air inlet tube has
a slight downward slope to the outside. The downward slope
is necessary to prevent the entry of rainwater. Attach outside
mounting plate to exterior wall with (4) #10 x 1 1/2" (38mm)
screws provided.
3. Apply furnace cement to 4" (102mm) diameter flue outlet collar
on combustion chamber and to 4" (102mm) diameter collar on
vent cap. Attach 4" (102mm) diameter flue outlet tube onto flue
outlet collar on combustion chamber. Attach vent cap into the 4"
(102mm) diameter flue outlet tube. Attach vent cap to outside
mounting plate with (3) #10 x 1/2" (13mm) screws provided.
4. Installation is completed.

reassembly and resealing Vent-air intake system
When vent-air intake system is removed for servicing the furnace,
the following steps will assure proper reassembly and resealing of
the vent-air intake assembly.
1. Remove old furnace cement from flue outlet collar on combustion
chamber and collar of vent cap. Remove old furnace cement
from both ends of 4" (102mm) diameter flue outlet tube.
2. Remove old caulking beneath the edge of the outside mounting
plate. Apply new caulking beneath the edge of the outside
mounting plate. Use additional caulking to correct uneven wall
surface, such as clapboard.
3. Attach 6" (152mm) diameter air inlet tube onto the collar of air
drop assembly. Attach caulked, outside mounting plate into
the 6" (152mm) diameter air inlet tube. Position the outside
mounting plate so that 6" (152mm) diameter air inlet tube has
a slight downward slope to the outside. The downward slope
is necessary to prevent the entry of rainwater. Attach outside
mounting plate to exterior wall with (4) #10 x 1 1/2" (38mm)
screws provided.
4. Apply furnace cement to 4" (102mm) diameter flue outlet collar
on combustion chamber and to 4" (102mm) diameter collar on
vent cap. Attach 4" (102mm) diameter flue outlet tube onto flue
outlet collar on combustion chamber. Attach vent cap into the 4"
(102mm) diameter flue outlet tube. Attach vent cap to outside
mounting plate with (3) #10 x 1/2" (13mm) screws provided.
5. Reassembly and resealing vent-air intake system is completed.
