Check that material meets local codes including fire stopping requirements. Some local
jurisdictions require a minimum initial length of pipe be exposed or accessible for
inspection. Pipe clearances - no IBC requirements; follow local codes. All piping must be
liquid and pressure tight.
Ensure all venting components are clear of burrs/debris prior to assembly. Clear plastic
debris left in the combustion air piping to avoid intake into the fan.
Secure joints using appropriate solvent cement to bond the respective pipe material
(Canada: CPVC cement approved under ULC-S636, in accordance with its manufacturer
instructions; USA: PVC (ASTM D2564), or PVC/ABS (D2235) - Use transition glue
anywhere that PVC and CPVC are joined. 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.
Check that vent connections are 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 and water
solution .the installer must fill the condensate trap prior to testing.
To drive the fan into manual high speed operation for vent leak testing, from the touchscreen
controller Main Menu go to
Diagnostics
>
Test Operation
>Set
Vent Test
to
On
. 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. We suggest attaching a tag on the vent line near the condensate drain tee with the type
of test, the date and the installer’s name.
3.5.5 Venting passage through ceiling and floor
Confirm material meets local codes including fire stopping requirements.
Check the local jurisdiction on the minimum initial length of pipe that should be exposed
or accessible for inspection.
Follow the local codes for pipe clearances - no IBC requirements.
Ensure that piping is liquid and pressure tight.
