Do not open the drain valve without connecting a hose so that
water can be diverted to an area where water damage is not a
problem. Use a at head screwdriver to open and close the drain
valve. Do not remove the drain valve from the unit without rst
draining the water heater. ONLY remove the drain valve by hand.
Failure to follow these instructions could result in leakage or
property damage. Such damages ARE NOT covered by product
warranty.
Figure 18 - Closing the Drain Valve
Part 5 - Venting
The heater must be vented as detailed in this section. Ensure
exhaust vent and intake piping complies with these instructions
regarding vent system. Inspect nished exhaust vent and intake
piping thoroughly to ensure all joints are well secured, airtight,
and comply with all applicable code requirements, as well as the
instructions provided in this manual. Failure to properly install the
vent system will result in severe personal injury or death.
A. General
This heater is certied as a “Category IV” appliance and requires
a special venting system. The vent system will operate with a
positive pressure in the pipe. Exhaust gases must be piped directly
outdoors using the vent materials and rules outlined in these
instructions. Do not connect vent connectors serving appliances
vented by natural draft into any portion of mechanical draft
systems operating under positive pressure. Follow the venting
instructions carefully. Failure to do so will result in substantial
property damage, severe personal injury, or death.
Exhaust and intake are to be piped separately. This heater cannot
share a common exhaust or intake with multiple appliances.
Failure to follow these instructions will result in substantial
property damage, severe personal injury, or death.
1. Installation should be made in accordance with the regulations of
the Authority Having Jurisdiction, local code authorities, and utility
companies which pertain to this type of water heating equipment.
2. Install the venting system in accordance with these instructions
and with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, CAN/
CGA B149, and / or applicable provisions of local building codes.
3. This water heater must be vented with materials, components,
and systems listed and approved for Category IV appliances.
NOTE: To avoid contamination often contained in indoor air, it is
best to pipe all intake combustion air directly to the outdoors.
NOTE: Care must be taken to prevent condensate freezing in the
exhaust vent pipe system. See local, state, provincial, and national
codes for best practices to prevent condensate freezing in the
exhaust vent pipe system.
Improper seating of vent pipe gaskets can cause eventual gasket
failure and exhaust gas leakage. Ensure the exhaust vent pipe is
properly beveled and seated before insertion into the ue adapter.
Failure to do so could result in property damage, severe personal
injury, or death.
Due to the extreme ammability of most glues, cements, solvents,
and primers used to join plastic exhaust vent and intake pipes,
explosive solvent vapors must be cleared from all vent piping before
start-up. Avoid using excess cement or primer, as this may pool in the
vent pipes. Vent assemblies should be allowed to cure for a period of
at least 8 hours before powering a connected appliance. Failure to
follow these instructions will result in substantial property damage,
severe personal injury, or death. It is the installers’ responsibility to
understand the hazards associated with explosive solvents and take
the necessary precautions to avoid these risks.
It is required to insert the provided exhaust and intake screens into
the vent terminations to prevent blockage caused by debris or birds.
Failure to keep terminations clear could result in property damage,
severe personal injury, or death.
• DO NOT insulate the rst three (3) linear feet of the exhaust vent
run.
• CPVC, Polypropylene, or Stainless
Steel pipe material MUST be used
if the rst three (3) linear feet of
the exhaust vent run is insulated or
passes through an enclosed space
greater than 6” in length, such as a
wall.
• If CPVC is used to meet these
requirements, the balance may be
installed with approved PVC pipe.
• If Polypropylene or Stainless Steel
is used to meet these requirements, the balance of the vent run
must be installed with the same material.
• Failure to comply with this warning could result in property
damage, severe personal injury, or death.
