Gas Flow

 

 

To check for proper gas flow to the combustion chamber, 

determine the Btu input from the appliance rating plate.

 

 

Divide this input rating by the Btu per cubic feet of 

available gas. Result is the required number of cubic 

feet per hour. Determine  the flow of gas through the 

gas meter for two minutes and multiply by 30 to get the 

hourly flow of gas.

 

 

Gas Pressure Adjustment

 

 

− Check gas line pressure with unit firing at maximum 

rate. A minimum of 5" (127mm) w.c. for natural gas 

or 11" (279mm) w.c. for LP/propane gas should be 

maintained for proper unit operation.

 

 

− After line pressure has been checked and adjusted, 

check regulator pressure. Adjust manifold pressure 
to values specified on the unit rating plate. See 
figures 8, 9, and 10 for gas pressure adjustment 
screw location. A natural gas to LP/propane gas 
changeover kit is required to convert unit in the field. 

Refer to installation instructions provided with 
changeover kit for conversion procedure.

 

 

Limit Control Switch

 

 

The limit control switch(es) are factory-set and are not 

field-adjustable.

 

 

Louver Vane Adjustment

 

 

The SEP series unit heaters are provided with adjustable 

louver vanes. Air flow from the unit can be directed down, 

straight, out, up, or any combination of these.

 

 
 

WARNING

 

 

DO NOT CLOSE the bottom three lou-

vers on SEP. Premature failure to the 

heat exchanger can occur.

 

 

 
 

Combustion Air Pressure Switch

 

 

This pressure switch checks for proper combustion air 

inducer operation before allowing an ignition trial. The 

switch is factory

−set and no field adjustment is necessary.

 

Service

 

 

CAUTION

 

 

 

The unit heater and vent system shall be inspected 

once a year by a licensed professional service 

technician, or equivalent.

 

 

LUBRICATION

 

 

  Combustion air inducer motor bearings are 

pre

−lubricated  and  sealed.  No  further  lubrication 

is necessary.

 

 

  Fan motor bearings should be lubricated 

according to manufacturer’s instructions on each 

motor. If no instruction is provided, use the 

following as a guide: motors with oiling ports are 

pre

−lubricated  for  an  extended  bearing  life, 

re

−lubricate  with  a  few  drops  of  SAE  No.  10 

non

−detergent oil once e

very two years.

 

 

BURNERS

 

 

  Periodically examine burner flames for proper 

appearance during the heating season.

 

 

  Before each heating season examine the burners 

for any deposits or blockage that may have 

occurred.

 

 

 Clean burners as follows:

 

 

  Turn off both electrical and gas supplies to unit.

 

 

  Disconnect gas supply piping, high tension 

and sensor leads. Remove gas manifold. 

Remove burner tray.

 

 

  Clean burners as necessary. Make sure that 

burner heads line up properly to ensure flame 

crossover. Check spark gap on electrode and 

adjust if required. The gap should be 

between  0.110" and 0.140" (2.8 mm to 3.6 

mm). The gap may be checked with 

appropriately sized twist drills or feeler 

gauges.

 

 

  Reinstall burner tray, gas manifold, high 

tension and sensor leads. Reconnect gas 

supply piping.

 

 

  Restore  electrical  power  and  gas  supply.

 

Follow lighting instructions to light unit. Check 

burner flame.

 

 

 

 

 

 

 

 
 

Turn off gas and electrical power to unit before 

per-forming any maintenance or service 

operations  on this unit. Remember to follow 

lighting instructions when putting unit back into 

operation after service or maintenance.

 

DO NOT CLOSE the bottom three louvers 

on SEP. Premature failure to the heat 

exchanger can occur.
