Page 6: Description Of System And Components
DESCRIPTION OF SYSTEM AND COMPONENTS System Description iHEAT is an electronically controlled gas/air modulation system that can be utilized with the SC80 burner to provide a variable heat source for an appliance. The components of the system include: a fan-assisted gas burner, a modulating gas valve, and an electronic control module that varies the speed of the burner fan and the gas flow rate through the gas valve. -
Page 7: Installation
INSTALLATION Mounting the Burner Enclosure The burner ships with mounting holes to bolt to the underside of the oven floor. These holes can support the full weight of the burner and enclosure. To mount the burner into the oven, first remove the front cover by loosening or removing the four nuts as shown: Nuts Figure 1 - Burner Cover... - Page 8 Separate the enclosure cover from the rest of the burner. Next, locate the mounting studs on the rear of the oven floor as pictured below: Figure 2 - Oven Floor Mounting Studs With the open side of the enclosure facing you, install the air tube into the hole shown above and put two bolts with washers into the holes shown below: Figure 3 - Inside of Burner Enclosure We recommend using two socket head hex screws and two washers under each head (provided with oven).

Page 9: Sizing And Inspection Of Gas Piping
Sizing and Inspection of Gas Piping GAS LEAK HAZARD Liquefied petroleum gas is heavier than air. All connections should be checked for leaks using a soapy solution applied to gas connections. Leaking gas will settle in low lying areas such as basements and trenches. - Page 10 The piping should be so installed as to be durable, substantial and gas tight. It should be clear and free from cutting burrs and defects in structure or threading. Aluminum tubing should not be used for the main gas supply. Joint compounds (pipe dope) should be used sparingly on male threads only and be approved for all gases.
- Page 11 Table 1 - Pipe Sizing Chart for Natural Gas (0-0.5 psi) with Straight Schedule 40 Metal Pipe Pipe Sizing Chart for Liquid Propane (11” w.c.) with Straight Schedule 40 Metal Pipe The following chart is based on 11” w.c. inlet pressure and a pressure drop of 0.5” w.c.. Special use: Piping sizing between single or second stage (low pressure regulator) and appliance.

Page 12: Electrical Wiring Of Burner
Before turning gas under pressure into piping, all openings from which gas can escape should be closed. Immediately after turning on gas, the system should be checked for leaks. This can be done by watching the 1/2 cubic feet test dial and allowing 5 minutes to show any movement, or by soaping each pipe connection and watching for bubbles. -
Page 13: As-Shipped Initial Burner Settings
AS-SHIPPED INITIAL BURNER SETTINGS This burner comes with the proper settings for a small dome oven. If, after installing the burner into the oven and testing the operation of the burner, anything is not functioning as it should, contact Wayne Combustion Systems Customer Support for further direction. -
Page 14: Dip Switches
Technicians: To calibrate the blower, complete the following steps once: Turn off power to the burner system, and wait for LEDs on the iHEAT board to go out. Position the dip switches on the iHEAT board such that dip switch 8 is on and all others are off. ... - Page 15 low pressure setting when following the directions below. The valve must be mounted with the modulating coil horizontal. The maximum rated inlet pressure to the gas valve is ½ psi (14” w.c.). The valve will be damaged if higher gas pressure is applied. The gas valve controls the pressure of the gas supplied to the burner in order to adjust the burner’s firing rate.

Turn the low pressure nut counterclockwise to reduce the pressure; turn clockwise to increase the pressure. Adjust until the desired pressure setting is achieved. Careful! Reducing the pressure too much or too quickly may cause the burner to go out. If this happens, turn the small nut clockwise ¼... -
Page 17: Diagnostic Lights
When the iHEAT board’s relay closes its contacts, 24 VAC is supplied to the ignition control. When this happens, the ignition control’s diagnostic LED will flash rapidly while the ignition control begins sparking. After successful ignition, the LED will light green and remain lit as long as a flame is detected. If the burner fails to light, the control will wait for the interpurge time, then spark again. -
