WALL HUNG CONVERSION

This boiler is certifi ed to be either mounted on the fl oor
as supplied, or mounted on a wall.
For wall mounting, perform the following steps.
1. Ensure that the desired location provides adequate
room for the clearance, see Table 1, venting, and
servicing.
2. Remove the right stainless steel panel, and
discard.
3. You will see that underneath the panel, the boiler frame
has mounting holes, designed for wall attachment.
4. The boiler must be mounted so the lag bolts enter
the studs of the wall. If this is not possible use a 3/4"
thick of plywood approximately 24 in, 610 mm, wide
by 36 in, 914 mm, high.
5. Install two #14-3" lag bolts three quarters of the
way into the surface, to the height you desire for
mounting.
6. Lift the boiler onto the wall, and tighten the top lag
bolts.
7. Once the unit is level, install the bottom two #14-3"
lag bolts.
8. Remove the Air Inlet Pipe assembly and Metering
elbow from the gas valve-venturi assembly, Figure
44.

9. Remove the two screws attaching the gas valve-
venturi assembly to the side of the blower and rotate
the valve 90° so the 1/2" threaded connection is
pointing down, Figure 45. Pay close attention to how
the cork gasket is aligned.
