must be used.
WARNING
• Before connecting the gas supply, determine the gas type and pressure
for the water heater by referring to the rating plate. Use only the same
gas type indicated on the rating plate. Using a different gas type will
result in abnormal combustion and malfunction of the water heater.
Gas supplies should be connected by a licensed professional only.
• The appliance and its gas connection must be leak tested before
placing the appliance in operation.
• The water heater cannot be converted from natural gas to propane or
vice versa without the supplied gas conversion kit. Do not attempt a
field conversion of the water heater without a the gas conversion kit.
Doing so will result in dangerous operating conditions and will void the
warranty.
NTI is not liable for any property damage and/or personal injury resulting
from improper conversions.

Return Air Ducting
The return air may be delivered to the
appliance via:
a) either side;
b) the back;
c) the bottom; or
d) any combination thereof, provided, in
all cases, that access to at least one side
door remains clear (24" min.) for blower
access and maintenance.

NOTE: For details and recommendations on side, back or bottom return ducting see
GF200 Installation Manual.
In all installations, an appropriate air filtration system is recommended and
must meet test requirements in UL 900. Failure to install and properly main-
tain such a system could lead to damage to and/or premature failure of the
space heating components.
In all cases, care must be taken to ensure that return ducting is sealed against
the inlet, such that the entire air steam is directed through the air filter. Failure
to do so could cause damage to the air moving equipment and clogging of
the heating and/or cooling coils.

Exhaust Vent Materials
From factory, the GF200 operates at water temperatures exceeding 150°F,
6
resulting in the potential for exhaust temperatures to exceed 149°F.
As such, high-temperature vent pipe material (CPVC or polypropylene; see table
below) must be used for the first 3 feet (2" venting) or 0.5 feet (3" venting).
If such materials are unavailable, see the Venting section of the GF200 manual for
instructions on how to limit the maximum water temperature set point.
Venting requirements differ in the US and Canada. Consult the following chart
or the most recent edition of ANSI Z223.1/NFPA 54 or CAN/CGA B149.1, as
well as all applicable local codes and regulations when selecting vent pipe
materials. Do not use cellular core PVC (ASTM F891), cellular core CPVC, or Radel®
(polyphenolsulfone) for the exhaust vent.
Locale Recommended Vent Materials
• PVC Schedule 40 (Solid core)
USA
• CPVC Schedule 40 or 80 (Solid core)
• Approved Polypropylene*
• Type BH Special Gas Vent Class IIA (PVC)
Canada**
• Type BH Special Gas Vent Class IIB (CPVC)
• Type BH Special Gas Class IIC (Polypropylene)
* Approved polypropylene systems include: Duravent Polypro (Single Wall): 2PPS-
xxx (2in), 3PPS-xxx (3 in) / Centrotherm Innoflue SW: ISxx02xx (2 in), ISxx03xx (3 in)
/ Centrotherm InnoFlue Flex: IFVL02XXX (2 in). Refer to the manufacturer's litera-
ture for detailed information.
** For installation in Canada, field-supplied plastic vent piping must comply
Vent
with CAN/CGA B149.1 (latest edition) and be certified to the Standard. For Type
BH Gas Venting Systems, ULC-S636. Components of this listed system must not
be interchanged with other vent systems or unlisted pipes or fittings. All plastic
components and specified primers and glues of the certified vent system must
be from a single system manufacturer and must not be intermixed with another
system manufacturer's parts. The supplied vent connector and vent termination
are certified as part of the water heater.
