Typical Installation

The Illustration below shows a typical installation of the
GSP tube heater. The installation drawing shown has a
straight horizontal venting arrangement and specifies the
minimum space required for maintenance, as well as the
allowable range of distances between the two suspension
points.
Detailed venting arrangements are illustrated in following
portions of this section.

VENTING

• Venting must be in compliance with the latest edition
of the National Fuel Gas Code (ANSI Z223.1 latest
edition: or the authority having jurisdiction.)
• Uninsulated single-wall metal pipe shall not be used
outdoors in cold climates for venting of these heaters
as specified by Section 7.8 of the ANSI Z223.1NFPA 54
National Fuel Gas Code-latest edition.
• For the installation of a single-wall metal pipe through
an exterior combustible wall, refer to the latest edition
of the National Fuel Gas Code or the authority having
jurisdiction.
• In regions of the country where prevailing winds are
consistently higher than 40 mph (64.4 kmh), it may be
necessary to terminate the vent system above the roof
level.
Other venting references can be found in equipment
volume of the ASHRAE Handbook.

General Guidelines

Regardless of the venting arrangement that will be
connected to the heater, the following general guidelines
for venting must be followed:
1. The installation must conform with local codes or in
the absence of local codes with the National Fuel Gas
Codes, ANSI Z223.1/NFPA 54, Natural Gas and Propane
Installation Code, CSA B149.1 for Canada.
2. Appliance input ratings are based on sea level operation
need not be changed for operating up to 2,000 feet
(609.9m) elevation. For operation at elevations above
2,000 feet (609.9m) contact manufacturer for specified
deration condition for Canada and the United States.

3. The appliance and its main gas valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of ½psi (3.5kPa).
The appliance must be isolated from the gas piping
system by closing equipment shutoff valve during
pressure testing of the gas supply piping system at test
pressures equal to or less than ½psi (3.5kPa).
(WARNING) Materials and items, when stored under
this heater, will be subjected to radiant heat and could
be seriously damaged.
4. All horizontal venting sections must slope away from
the heater at a rate of ¼" per foot (0.635 cm per 0.3m)
5. The total length of vent pipe (horizontal and vertical
runs combined, plus the length of the exterior
termination) must not exceed 25 feet (7.62 m), and
must not be less than 3 feet (0.9144 m).
6. The vent terminal, mounted outside of the building,
should not be located above walkways. Condensate
produced during operation of the heater could drip
onto the walkway and could form ice during cold
weather.
7. Be sure that the venting installation is in accordance
with all applicable local codes and recommendations of
the local gas company.
8. DO NO connect this heater to a separate chimney, and
DO NOT common vent with any other fuel burning
appliance. Gas appliances must not be connected to
a chimney flue serving a separate solid-fuel burning
appliance.
9. Maintain a minimum of 1-inch (2.54 cm) clearance from
combustibles around all vent pipes.
10. Seal all vent pipe connections with high temperature
silicone sealant and secure each connection with three
sheet metal screws.
A. VERTICAL VENTING THROUGH THE ROOF
This heater, when vertically vented, must be installed with
the approved venting system. For vertical vent installations
the GSP45 tube heater is certified as a category I appliance.
NOTE: For applications where the heater must not be
connected to a separate chimney, it must be
installed using the venting system as specified
below.
1. When venting the heater to outside of building through
a roof, use 4 inch (10.16 cm) O.D. single-wall metal
pipe. This is to be constructed of galvanized sheet metal
or other approved noncombustible, corrosion-resistant
material as indicated by state and/or local codes.
2. A vent passing through a combustible roof shall extend
through a 2-inch (5.08 cm) clearance roof thimble.
Double-wall, Type B vent must be used for the portion
of the vent system which passes through the roof. An
approved vent cap (such as Leslie "VeraCap" Type B)
must be attached to the end of the flue.
