CONNECT GAS LINE
WARNING:
USE NEW BLACK IRON OR STEEL PIPE. INTERNALLY
TINNED COPPER OR COPPER TUBING CAN BE USED
PER NATIONAL FUEL CODE, SECTION 2.6.3, PROVIDING
GAS MEETS HYDROGEN SULFIDE LIMITS, AND WHERE
PERMITTED BY LOCAL CODES. GAS PIPING SYSTEM MUST
BE SIZED TO PROVIDE MINIMUM INLET PRESSURE (LISTED
ON DATA PLATE) AT THE MAXIMUM FLOW RATE (BTU/
HR). UNDUE PRESSURE LOSS WILL OCCUR IF THE PIPE IS
TOO SMALL.
A MANUAL SHUTOFF VALVE MUST BE INSTALLED
UPSTREAM OF THE APPLIANCE. UNION TEE AND
PLUGGED 1/8” NPT PRESSURE TAPPING POINT
SHOULD BE INSTALLED UPSTREAM OF THE APPLIANCE.
A SEDIMENT TRAP SHOULD BE INSTALLED UPSTREAM
TO PREVENT MOISTURE AND CONTAMINANTS FROM
PASSING THROUGH THE PIPE TO APPLIANCE CONTROLS
AND BURNERS. FAILURE TO DO SO COULD PREVENT THE
APPLIANCE FROM OPERATING RELIABLE.
NOTICE: A qualified gas appliance installer must connect
the heater to the gas supply. Consult all local codes.
IMPORTANT: Hold heater valve firmly with a wrench to
prevent movement when connecting to inlet pipe. Always
use an external regulator for all propane/LPG heaters and
high pressure one to two-pound systems only, to reduce the
supply tank pressure to a maximum of 13” w. This is in
addition to the internal regulator in the heater valve.
CHECK GAS TYPE: The gas supply must be the same as
stated on the heater’s rating plate. If the gas supply is
different, DO NOT INSTALL THE HEATER. Contact your
dealer for the correct model.

ELECTRICAL WIRING (MILLIVOLT)
The millivolt valve is a self-powered combination gas control
THAT DOES NOT REQUIRE 110V AC TO OPERATE.
CAUTION:
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN
SERVICING CONTROLS. WIRING ERRORS CAN CAUSE
IMPROPER AND DANGEROUS OPERATION. VERIFY
PROPER OPERATION AFTER SERVICING.
CONNECT OPTIONAL WALL SWITCH
1. Use 18 awg, two-wire cable, 15 feet maximum length.
2. At one end of the cable, connect both wires to the wall
switch. At the other end, connect one wire to TP/TH
and one wire to TH, or connect the wall switch to the
two male (0.25”) terminals on the left side of the unit.
CHECK SYSTEM OPERATION
The millivolt system and individual components may be
checked with a millivolt meter having a 0-1000 mV range.
Conduct each check shown in chart below by connection
meter test leads to terminals as indicated.
A. Complete Millivolt System Check (“A” Reading -
Thermostat contacts closed - Control Knob “ON” - Main
burner should turn on)
• If the reading is more than 100 millivolts and the automatic
valve still does not come on, replace the control.
• If the closed circuit reading (“A” reading) is less than 100
millivolts, determine cause for low reading, proceed to
section B below.
B. Thermopile Output Reading Check (“B” Reading -
Thermostat contacts open - Main burner off)
• Check gas pressure to the unit. If gas pressure is within
minimum and maximum on data plate, then check pilot
voltage, 325 millivolts minimum. If the minimum millivolt
reading is not obtainable, replace pilot.
