Warnings
The boiler door must be in place during operation, maintenance and service
excepted.
In addition to preventing ingestion of chemical contaminants, ensure air intake
terminals are not installed in locations where contamination might occur due to
ingestion of particulate foreign material (dust, dirt and debris).
Configure intake air openings, so that rain or other forms of moisture cannot
enter the air intake piping system. Otherwise serious damage to the boiler may
result.
Notes
When installing air intake piping, ensure that a "trap" is not formed in the piping
causing a build-up of water and blockage of intake air. Such blockages will
cause a boiler safety shut-down.
Filters require checking and cleaning or replacing on a regular schedule based
on the severity of the problem.
Exhaust venting installation
Exhaust venting must slope down towards the boiler with a pitch of at least ¼" per foot (PP vent:
follow PP manufacturer requirements for slope), so condensate runs back towards the trap.
Exhaust piping is inserted directly into the left connector on the top of the boiler, then runs
horizontally or vertically to the outdoors. Screen material can be placed at the outlet as
appropriate for the environment (e.g., insects, dust).
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.
