PART 11 INSTALLATIONS
WARNING
Before starting the boiler smell near the floor, the interior of the boiler and around the boiler for any gas odors or any unusual odor. If
there is any sign of a gas leak, do not proceed with startup. Repair all the leaks before attempting to start the boiler
WARNING
Propane boilers ONLY
– Your local propane supplier adds an odorant to the propane gas to allow for propane gas leak detection. In
some cases, the added odorant can fade and the gas may not give off any noticeable odor. Before startup have the local propane
supplier check for the correct odorant level in the gas.
11.1 CHECKING THE INSTALLATION

Inspect the connections for water, gas and electricity.

Inlet gas pressure should
be 7” W.C. for natural gas and 11” W.C. for propane.

With the boiler off, open the main gas supply valve and vent the trapped air from the piping leading to the boiler. Confirm that
all gas connections to the heater are tight and that there are no missing test plugs.

Refer to Section 8.3 Gas Valve Adjustment Procedure of the manual for recommendations on setting combustion characteristics
11.2 CHECKING THE INSTALLTION

Check the boiler wiring to see that it agrees with the wiring diagram supplied.

Confirm that all terminal strips and field connections are identified.

With the boiler running, check for flue gas leaks around the flue outlet.

Repair any leaks prior to proceeding to the next step.

At the factory, adjustments were made to achieve proper input and acceptable burner performance at full input and at minimum
input.
11.3 INSPECT & RECHARGE CONDENSATE COLLECTION & NEUTRALIZING RESERVOIR
1. Inspect the connections to the neutralizer/ condensate box.
2. Remove screws holding lid on to condensate collection box. Remove lid from the condensate collection box.
3. Fill with fresh water until the water begins to flow out of drain. Recharge with neutralizer medium as required.
4. Re-install the lid and hold-down screw on the neutralizer condensate collection box.
5. Inspect the condensate neutralizer supplied on site and confirm that it contains sufficient calcium carbonate to operate effectively
to neutralize condensate to required level.
6. Check pH level of condensate.
WARNING
The neutralizer condensate collection box must be filled with water to prevent flue gas emissions from escaping during boiler
operation.
CAUTION
A leak in a boiler heating
“System” will cause the fill system to introduce fresh water constantly, which may cause the tubes to
accumulate a lime/scale build up. Lime/scale buildup leading to heat exchanger failure is NOT covered by warranty.
11.4 HEATING BOILER INSTALLATIONS
It is recommended that this appliance be installed in a primary/secondary reverse return piping system for proper operation. Before
beginning the installation, consult local codes for specific plumbing requirements. The installation should provide unions and valves at
the inlet and outlet of the appliance so it can be isolated for service. An air separation device must be supplied in the installation piping
to eliminate trapped air in the system. Locate a system air vent at the highest point in the system. The system must also have a properly
sized expansion tank installed. Typically, an air charged diaphragm-type expansion tank is used. The expansion tank must be installed
close to the boiler and on the suction side of the system pump (appliance Inlet) to ensure proper operation.
Caution: This appliance
should not be operated at less than 30 PSIG . Water piping must be supported by suitable hangers or floor stands, NOT by the
appliance. Pipe systems will be subject to considerable expansion and contraction. Pipe supports could allow the pipe to slide resulting
in noise transmitted into the system. Padding is recommended. The boiler pressure relief valve must be piped to a suitable floor drain.
See Part 4.
CAUTION
1)
A leak in a boiler “System” will cause the “System” to intake fresh water constantly, which may cause the tubes to accumulate
a line/scale build up. This will be a
NON-WARRANTABLE FAILURE
2) If boiler pumps are not operated when treated water is introduced a corrosion cell may be created in the boilers leading to a
failure which is not covered by warranty.
3) Target water quality of treated water to be stable and neutral with regards to corrosive/scaling properties. Damage to or failure
of the heat exchanger as a result of scaling or corrosive water quality is not covered by warranty.
