EXALT NATURAL TO PROPANE CONVERSION INSTRUCTIONS
3
NOTICE
The Exalt boiler has a length of acoustic foam already in-
stalled in the air inlet adaptor. DO NOT remove this
3. Insert the length of acoustic foam (supplied), into
the 7" pipe length.
4. Use either a straight coupling or elbow to continue
the air inlet installation. Refer to the Vent Supple-
ment for full details on the installation of air and
vent pipes.
3. Removal of Natural Gas Venturi
1. Remove the silicone tube from the air inlet elbow,
then remove the air inlet elbow.
2. Rotate the venturi interface approximately 60°
clockwise to release the clamping mechanism and
remove the venturi interface.
3. Remove the gas valve to venturi pipe by loosening
the nuts at both ends of the pipe with an adjust-
able wrench.
NOTICE
There are gaskets at both ends of the gas valve to venturi
pipe. These gaskets must be replaced along with the pipe.
4. Using a 10 mm socket and ratchet, remove the
three (3) bolts securing the venturi to the fan as-
sembly and remove the natural gas venturi from
the unit, making sure not to damage the blower
O-ring gasket.
4. Install the Propane Venturi
1. Verify the following when aligning the propane
venturi:
1. The UP arrow on the plastic housing is pointing
upward.
2. The threaded connection for the gas piping is in
the correct orientation for re-tting the gas pipe.
WARNING
!
Failure to retain the O-ring gasket between the ventu-
ri and the blower will cause an improper seal resulting
in a potential risk of a gas leak. A gas leak can result in
substantial property damage, serious injury, or death.
2. Install the new venturi/blower gasket into the
blower.
WARNING
!
Ensure the proper venturi for the model is installed
per Table 1. Failure to comply will affect input rate
and combustion of the boiler which can result in sub-
stantial property damage, serious injury, or death.
NOTICE
Do not use adhesive on any gaskets or O-rings during the re-
assembly process.
3. Using a 10 mm socket and ratchet, reinstall the
three (3) bolts securing the venturi to the fan as-
sembly
4. Reassemble the gas valve to venturi pipe to the
gas valve and venturi taking care to ensure that the
gaskets are seated properly before tightening the
nut.
5. Install the venturi interface on the venturi and ro-
tate counterclockwise until locked into place.
6. Install the air inlet elbow then attach the silicone
tube.
WARNING
!
Failure to properly install the air inlet elbow and at-
tach the silicone tube can affect combustion of the
boiler which can result in substantial property dam-
age, serious injury, or death.
7. Open the manual gas shut o valve to the unit.
Before placing the boiler back into operation, test
all gas connections for leaks and repair if leaks are
found.
WARNING
!
Do not check for gas leaks with an open flame. Use a
bubble test. Failure to test for gas leaks can result in
substantial property damage, serious injury, or death.
8. Attach the Propane conversion label (Fig. 4) to the
side of the boiler and the rating label label (Fig. 5)
