Figure 24. GAS VALVE
16.1 SETTING MANIFOLD PRESSURE
MANIFOLD PRESSURE REGULATOR ADJUSTMENT and PRESSURE VERIFICATION PROCEDURE:
TOOLS REQUIRED
-Small Flat Blade Screw Driver
-2 mm (millimeter) allen wrench
-3 mm (millimeter) allen wrench
-
Manometer that measures inches of water column (“ W.C.)
-Volt Meter capable of reading AC and DC voltage in a range of 0 to at least 30 volts
INITIAL STEPS:
1)
The installer must verify that the heater being installed is of the correct fuel type for the
available fuel that is supplied for this installation. This includes any high altitude correction that
may be applicable for your installation.
Confirm site has adequate fuel supply to operate all gas fired
appliances, including this/these heater(s), at their maximum rated capacity simultaneously (at the same
time). Make sure gas lines and pressure regulators are of a capacity to deliver the correct line pressure
w
ithin the specified range for your fuel type (5” to 14” w.c. for natural gas and 12” to 14” w.c. for
propane or Propane fuel) to the heater’s gas line inlet connection, with all gas fired appliances on site
operating at the same time. If you are unable to achieve the stated line pressures during operation, you
will not be able to verify and/or adjust the gas manifold pressure setting on this heater, and the heater
will not operate correctly. If fuel pressure is too low, the heater will not have enough fuel to achieve its
maximum heat level. Alternatively, if the fuel line pressure is too high, the valve can be damaged.
2) Make sure all gas-fired appliances on site, other than this heater, are on and operating at the same time.
Otherwise, an inaccurate reading of manifold pressure may occur.
3) Make sure this heater is not operating and is turned off when you start this procedure.
WARNING
INSTALLER MUST VERIFY AND ADJUST, IF NECESSARY, THE MANIFOLD OPERATING PRESSURE OF THIS HEATER
ACCORDING TO THE INSTALLATION MANUAL AND RATING PLATE OF THIS HEATER.
FAILURE TO DO SO WILL VOID ALL WARRANTIES AND MAY CAUSE DAMAGE, INJURY AND/OR DEATH.
IF YOU HAVE ANY QUESTIONS CONCERNING THESE INSTRUCTIONS, CALL CALCANA AT 800-778-6729 BEFORE YOU VERIFY
AND/OR ADJUST THE MANIFOLD FUEL PRESSURE ON THE HEATER.
No one should work on or install this heater unless
they are a licensed/qualified and insured contractor trained in the appropriate trade or technical fields
(Gasfitting-HVAC-Electrician) related to the installation and/or service of this heater.
Person(s) who service and/or install this unit accept full liability and responsibility for its operation.
