As shown in the previous figure, the manifold contains 3 solenoids valves (SV) that are responsible
for the release of gas in each burner segment. This allows the unit to have 6 burner level stages
according to the solenoid combination:
Stage 1 – SV 1
Stage 2 – SV 2
Stage 3 – SV1 + SV2
Stage 4 – SV3
Stage 5 – SV1 + SV3
Stage 6 – SV1 + SV2 + SV3
The manifold is only available as one spare part. However, for maintenance purposes it may be
required to open the manifold. The Gas Seal is made of cork and is not available as an individual
spare part.
For maintenance purposes the process of disassembling the manifold has the following steps:
1. The manifold is already separated from the appliance. If not, follow the steps in Figure 15.
2. Remove the gas restrictor seal (4 screws) (see figure below)
3. Remove the front cover (12 screws)
4. Remove the cork seal
5. Remove the rubber seal from the reverse side of the manifold. Every time that the manifold
is disassembled, this seal must be replaced.
The new manifold allows the installer or technician to easily convert the appliance between natural
gas (NG) and Liquid Propane Gas (LPG). The appliance comes factory installed in NG configuration,
so if the unit is being used in a NG application, no additional modification is necessary. To operate
the unit with LPG, a gas restrictor must be installed, as detailed in the following figures.
