INSTALLATION
SL 30-175, SL 45-260 MODULATING GAS BOILERS
runs back towards the trap. support should be provided for intake and vent piping,
particularly so for horizontal runs (follow local code). You may have to insulate
exhaust piping where it passes through unheated spaces or underground, with
appropriate pipe insulation to prevent freezing of condensates. Contact Factory for
details.
Ensure all venting components are clean of burrs/debris prior to assembly.
Care is to be taken to avoid ingestion into the fan of plastic debris left in the
combustion air piping.
all joints must be secured. For CPVC in Canada, use ulC-s636 approved CPVC
solvent cement, in accordance with its manufacturer instructions. Follow the
cement manufacturer’s instructions closely when joining various components. For
PPs, connections shall be secured using approved retainer clips supplied by the
respective PPs manufacturer.
All vent connections must be liquid and pressure tight. Prior to firing the boiler,
and before any of the venting run is concealed by the building construction, the
installer must test the exhaust joints under fan pressure with the vent blocked,
using a soap/water solution. Installer must fill condensate trap prior to test.
remove the fan control harness plug as illustrated in the photos, and then block
the vent outlet so that the vent run will be under maximum fan pressure. Paint all
joints with an approved leak test solution just as you would joints in a gas line,
and make sure there are no leaks. good practice would suggest that the installer
attach a tag on the vent line near the condensate drain tee indicating the type of
test, the date and the installer’s name.
1.4.4 venting Passage Through Ceiling and Floor
•
Confirm material meets local codes including fire stopping requirements.
•
Pipe clearances - no iBC requirements; follow local codes.
•
all piping must be liquid and pressure tight.
1.4.5 Rooftop vent Termination
rooftop vents must terminate as follows:
•
the exhaust pipe can terminate in an open vertical orientation without concern
about rain infiltration; rain will drain away through the condensate trap.
•
if used, the intake air pipe is not typically drained, so it must be terminated
with a down-turned elbow (see Figure 4 ). the intake pipe does not need to
penetrate the roof at the same elevation as the exhaust (as shown); lower
down roof is oK.
Fan control harness plug
Unplugging fan control harness plug
will drive the fan into manual high
speed operation for vent leak test
WARNING
Condensate can cause
corrosion of metal roofing
components and other
roofing materials. Check
with the builder or roofing
contractor to ensure that
materials will be resistant to
acidic condensate. pH levels
can be as low as 3.0
