System 1738 Installation Methods20
System Repair
Inspect pipe for any damage such as cracking and
deep gouges. Locate the end of any pipe cracks and be
sure to cut at least 2” beyond the crack line to ensure it
is removed.
Carefully inspect any fittings for damage and remove
and replace them accordingly.
Repairs can be made by solvent welding new sections
of pipe and fittings. Follow all the solvent welding
instruction within this guide. However, installation
conditions during a repair vary greatly when compared
to a new installation. Repairs or cut-ins to an existing
system are typically done in confined spaces, on closed
end piping systems, and often have more humidity
present. All of these factors can inhibit the evaporation
of the solvent leading to increased set and cure times.
As such, IPEX recommends that the standard set and
cure times be increased by 50% for repairs or cut-ins.
Refer to set and cure tables in this guide.
When modifying or repairing aged PVC pipe, use only
wheel cutters or fine tooth saws that are new and
sharp. DO NOT use ratchet style cutters.
CAUTION
Maintenance
IPEX recommends that the System 1738 Flue Gas Venting
system be checked at least once per year by a licensed
Plumbing or HVAC service technician. This can be done
during any regular maintenance activities as required for
the heating appliance or any other time.
Vent Replacement
IPEX recommends the vent piping system be replaced
each time the heating appliance is replaced.
