Gas Supply Sizing
The vaporization of propane is affected by several factors: the
surface area of the container, the liquid level of propane,
temperature surrounding the container, and the relative
humidity. All of these factors are specific to a site. Therefore,
a degree of experience and judgment is required to select the
proper propane supply. Although experience is the best guide,
the following recommendations can be used as a starting
point. The table is based on experience in northern climates
where cold weather and high humidity are prevalent in the
winter. If more or less favorable conditions prevail at a specific
site, adjustments can be made on the basis of experience.
Recommended Gas Supply
TANK SIZE
500 gal. / 1892 litre
1000 gal. / 3784 litre
If more than one gas supply container is used per heater,
the containers must be manifolded together to allow vapor
withdrawal simultaneously from multiple containers. Manifold
system shall be in accordance with NFPA 58 or CSA B149.1.
Optional Accessories
Must be ordered separately

1. The heater has a 1 in. (25.4 mm) NPT pipe nipple at
the gas inlet of the heater.
2. Apply piping compound to the pipe.
3. Attach the regulator outlet to the heater with the
appropriate fittings. Tighten securely.
4. Connect the appropriate gas hose to the regulator
inlet.
5. Leak check the connections with an approved leak
detector.
6. When using this regulator and any hose, the
regulator needs to be set such that the supply
pressure at the heater inlet is 13.8 in. W.C. while
operating.
7. When storing or transporting the heater, ensure the
connector's fitting is protected from damage and
dirty entry.
WHEN USING NATURAL GAS
• A regulator should be used if the gas supply pressure
to the heater gas inlet is above the maximum inlet
pressure stated on the heater's dataplate.
• Connect the regulator nearest to the inlet of the
heater, using the appropriate connections.
