WARNING
In order to ensure proper operation
and efficiency of the device you have to connect
the boiler fume exhaust fitting to the exhaust and
fresh air adapters (loosely supplied in boiler). It is
recommended to install discharge systems approved
by Radiant.
WARNING
All termination kits must be located and
installed in accordance with local building code and
CSA B149.1 Natural Gas and Propane Installation
Code.
WARNING
For condensate collection please follow
the local codes.
› All exhaust runs shall be sloped such that any
condensate would move towards the combustion
chamber so that it can be collected and drained
via the internal condensate trap of the appliance
(Refer to section 1.1.18).
› All combustion air intake runs where possible
should be sloped in a manner to avoid rain
water, dust or foreign objects from entering the
appliance (Refer to section 1.1.18).
› In case of horizontal polypropylene co-axial
system installation, properly orientate the
horizontal co-axial terminal in relation to the
slopes inside the exhaust pipe and to protect
the combustion air pipe from adverse weather
conditions (Refer to section 1.1.18, sub-section
III (
a
)
and figure 20).
This appliance is certified to be installed using
polypropylene, PVC and CPVC. For Canada use
System 636 polypropylene, PVC and CPVC Type
BH Gas Venting Systems certified to ULC S636.
Types of venting configurations for this appliance
are, co-axial vent (pipe with in a pipe), co-linear
vent (separate pipes for exhaust and combustion
air), and single exhaust vent (uses room air for
combustion).
This appliance shall not be connected to a chimney
flue serving a separate appliance, designed to
burn solid fuel.
Use of cellular core PVC (ASTM F891), cellular
core CPVC, or Radel® (polyphenylsulfone) in non-
metallic venting systems is prohibited.
The vent for this appliance shall not terminate:
1) over public walkways; or
2) near soffit vents or crawl space vents or other
areas where condensate or vapor could create a
nuisance or hazard or cause property damage; or
3) where condensate vapor could cause damage or
could be detrimental to the operation of regulators,
relief valves, or other equipment.
Please refer to figure 14 for further clearances on
where to terminate the vent.
