G.4 Site Preparation
1. Identify the tie to be replaced by the tie duct, or the crib
for the crib ducts. Relative to the appropriate tie or crib,
prepare a foundation for the heater with ties, concrete pad,
or other suitable level mounting structure.
2. Note the location for the gas, electrical supply, and the
signal cable lines.
3. Refer to the local gas and electrical authority in order to
determine gas pipe and electrical line sizes.
4. At the heater, the gas inlet is a female 1” NPT pipe thread,
the power terminal block accepts #14 - #2 AWG wire sizes,
and the control and indicate wires connect to AAR 1/4”
post terminals.
G.5 Heater Installation
1. A typical complete system is composed of 4 parts, the
heater, a transition duct, a tie duct or crib duct set, and a
track duct set, each packaged separately.
2. Install the duct system components first, as per Switch
Heater Duct Installation Manual, part number 16359.
3. Remove shipping cover attached to combustion chamber
flange. Remove thermostat box from shipping cover and
discard cover.
4. Remove banding strap securing access panels. Open
combustion chamber access panel and remove loose
packaged contents including large gasket kit, and
if included with order, the precipitation detector, rail
thermostat and flexible gas line.
5. Lift heater, (565 lbs.), using lift pockets and place on the
foundation.
6. Level heater, adjusts leveling legs, and align with the
transition duct flange.
7. Fasten the heater and transition flanges together with the
supplied gasket kit.
8. Fasten heater legs to foundation using lag screws supplied
or suitable fasteners.
G.6 Gas Supply Piping and Minimum Pressure Drop
WARNING
WARNING. Personnel approved by the local gas
authority must perform gas line connection.
1. Nominal supply pressure, 5 to 20 psi, with no more than
20% pressure drop, with all connected loads operating.
2. The minimum recommended supply pipe size is 1”.
Determine required pipe size based on supply pressure,
length of run, and the total demand of all connected loads.
CAUTION
CAUTION. Undersized gas piping will affect the light off
reliability of any connected appliance.
3. The heater is supplied with an internally mounted supply
regulator and an external dirt trap. The dirt trap inlet has a
1” NPT female fitting.
4. Install a flexible gas line between the customer supplied
gas line and the dirt trap inlet.
5. Prior to firing the heater, bleed the gas lines of any air and
dirt through the opened dirt trap.
6. Reinstall the dirt trap cap and check all joints for leaks.
G.7 Electrical Power Connections
WARNING
WARNING.
Risk of electrical shock or electrocution.
Disconnect power at service.
Heaters must be wired in accordance with local
electrical codes.
The electrical grounding of the appliance shall be in
compliance with CSA C22.1, Canadian electrical code,
Part 1, or National Electrical Code, ANSI/NFPA 70.
Personnel approved by the local electrical authority
must perform electrical power connection.
IMPORTANT NOTE
Surge Protection Recommendations
This switch heater utilizes a number of processor-based control
systems, all of which are susceptible to damage from lightning
and other electrical surges. While every effort has been made to
ensure that the control systems have been adequately ‘hardened’
Thermon Heating Systesms, Inc’s surge mitigation efforts can only
be effective if ALL external remote circuits connecting to the switch
heater have been protected by primary surge protection devices in
accordance with the following generally accepted requirements for
surge protection of wayside signal equipment:
• Provide primary surge protection devices (standard signal air
gap arresters) on all external switch heater control I/O circuits.
These arresters should be located “upstream” of the switch
heater housing (within the signal housing, which interfaces to
the switch heater). It is essential to protect ALL circuits entering
or leaving the signal housing.
• Provide a primary surge protection device (commercial high
capacity MOV type) on the external switch heater ac power
feed. This surge protection device should be located “upstream”
of the switch heater in conjunction with the electrical service
