Table G: Maximum Equivalent Pipe Length

A minimum of 7" W.C. and a maximum of 10.5" W.C.

upstream pressure, under load and no-load condi-

tions, must be provided for natural gas, or a minimum

of 12" W.C. and a maximum of 13" for propane.

Gas Pressure Regulator

The gas pressure regulator is preset nominally at 4"

W.C. for natural gas, and 11" W.C. for propane.

Between the gas valve and the burners is a 1/8" pipe

plug. The pressure at this point, taken with a manome-

ter, should be about 3.7" W.C. for natural gas and

10.5" W.C. for propane. Low NOx models should be

3.9" W.C., natural gas only. If an adjustment is need-

ed, turn adjustment screw clockwise to increase

pressure, or counter-clockwise to decrease pressure.

For boilers with mechanical modulation gas valves

(Type H1 and H5) or two-stage gas valves (Type H3),

the gas pressure regulator is preset and sealed, and

not field adjustable. Pressure tap is provided on the

outlet side of the gas valve for measurement of gas

pressure in the manifold.

Venting of Diaphragm Gas

Components

Gas valves that are equipped with a gas bleed must be

vented to the outdoors as required by the National

Fuel Gas Code. Under NO circumstances shall bleed

lines terminate in the gas utilization equipment flue or

exhaust system.

General

Boiler should be located so that any water leaks will

not cause damage to any adjacent areas or structures.

See piping diagrams for proper water connections for

the type of boiler and system.

Pump Selection

In order to ensure proper hydraulics in your hydronic

heating system, adequate pump size must be select-

ed. We recommend that the pump be sized for 20°F

Delta T whenever possible. (Delta T is the temperature

Fig. 23: Bleed Line Connection Location

CAUTION:

The boiler and its manual shut-off valve

must be disconnected from the gas supply during

any pressure testing of that system at test pressures

in excess of 1/2 PSIG. Dissipate test pressure in

the gas supply line before reconnecting the boiler

and its manual shut-off valve to gas supply line.

FAILURE TO FOLLOW THIS PROCEDURE MAY

DAMAGE THE GAS VALVE. OVER PRESSURED

GAS VALVES ARE NOT COVERED BY

WARRANTY. The boiler and its gas connections

shall be leak tested before placing the appliance in

operation. Use soapy water for leak test do NOT use

open flame.

*Low NOx units not available for propane.
