Sizing Between First and Second Stage Regulator*

Maximum Propane Capacities listed are based on 2 psig pressure drop at 10 psig setting.

Capacities in 1,000 BTU/hour.

To convert to capacities at 15 psig settings - multiply by 1.130

To convert to capacities at 5 psig settings - multiply by 0.879

All propane gas equipment must conform to the safety stan-

dards of the National Board of Fire Underwriters, NBFU

Manual 58.

For satisfactory operation, propane gas pressure must be

11 inch WC at the furnace manifold with all gas appliances

in operation. Maintaining proper gas pressure depends on

three main factors:

1. Vaporization rate, depending on temperature of the liq-

uid, and “wetted surface” area of the container or con-

tainers.

2. Proper pressure regulation. (Two-stage regulation is rec-

ommended for both cost and efficiency).

3. Pressure drop in lines between regulators, and between

second stage regulator and the appliance. Pipe size will

depend on length of pipe run and total load of all appli-

ances.

Complete information regarding tank sizing for vaporiza-

tion, recommended regulator settings, and pipe sizing is

available from most regulator manufacturers and propane

gas suppliers.

Always use a pipe sealant approved for natural gas and LP

gas.

Refer to the following illustration for typical propane gas

installations and piping.

WARNING

F THE GAS FURNACE IS INSTALLED IN A BASEMENT, AN EXCAVATED

AREA OR A CONFINED SPACE, IT IS STRONGLY RECOMMENDED TO

CONTACT A PROPANE SUPPLIER TO INSTALL A GAS DETECTING

WARNING DEVICE IN CASE OF A GAS LEAK.

•

SINCE PROPANE GAS IS HEAVIER THAN AIR, ANY LEAKING GAS CAN

SETTLE IN ANY LOW AREAS OR CONFINED SPACES.

•

PROPANE GAS ODORANT MAY FADE, MAKING THE GAS UNDETECTABLE

EXCEPT WITH A WARNING DEVICE.

WARNING

AN UNDETECTED GAS LEAK WILL CREATE A DANGER OF EXPLOSION

OR FIRE.

IF THE PRESENCE OF GAS IS SUSPECTED, FOLLOW THE

INSTRUCTIONS ON THE COVER OF THIS MANUAL.

FAILURE TO DO SO

COULD RESULT IN

SERIOUS PERSONAL INJURY OR DEATH.
