GAS SUPPLY

 

GAS PRESSURE TEST

 

 

 

Verify that the appliance is supplied with the type gas specified on the rating plate. Consult factory for installations at altitude.

INLET PRESSURE: Measured at the inlet pressure tap on the appliance gas manifold. The pressure tap is located upstream of the redundant gas valve and down stream of the field installed gas cock.

Maximum inlet gas pressure must not exceed the value specified. Minimum value listed is for the purposes of input adjustment.

MANIFOLD PRESSURE: Manifold pressure is a differential pressure measurement made between the high and low pressure taps at the gas orifice and the pressure in the transition chamber where the gas is supplied to the inlet of the combustion air blower. All manifold gas pressures are noted at full firing rate. The controls on this appliance may fire the burner from 25% up to 100% of rated input, based on system demand. Manifold gas pressure will be reduced as burner input is reduced. All reference gas pressure measurements must be made at 100% of rated burner input. The gas manifold pressure is pre-set at the factory by the ratio gas valve. Adjustment of manifold pressure is not normally required for proper operation. The adjustment point on the ratio gas valve is set at the factory. DO NOT attempt to adjust the settings on the ratio gas valve. Improper adjustment of the ratio gas valve may cause incomplete combustion or non-warrantable burner damage.

1.The appliance must be disconnected from the gas

during any

pressure

testing

of that

system

at a

test pressure

in excess

of 1/2

PSIG (3.5kPa).

 

 

 

 

2.The appliance must be isolated from the gas supply piping system by closing a manual shutoff valve during any pressure testing of the gas supply

piping system at test pressures equal to or less than 1/2 PSIG (3.5kPa).

3.The appliance and its gas connection must be leak-tested before placing it in operation.

GAS CONNECTION

1.Safe operation of unit requires properly sized gas supply piping. See gas line sizing data.

2.Gas pipe size may be larger than appliance connection.

3.Installation of a union at the appliance gas line connection is required for ease of service and removal of the gas train.

4. Install a manual main gas shutoff

valve,

outside

of

the appliance gas connection and

before

the

gas

valve, when local codes require.

 

 

 

5.A trap (drip leg) MUST be provided in the inlet of the gas connection to the appliance.

6.The diaphragm gas valve has a bleed port that requires venting to atmosphere, outside the building.
