Harman PB 105, Инструкция по установке и эксплуатации, Страница: 7 / 40

Design:
The first thing that needs to be done is deciding where and how
the boiler will be installed.
Things that need to be taken into consideration are the intended
use of the boiler for example, is the boiler going to be used
as your primary heating system or is it going to be used as
a secondary or backup heating system. If it is to be used in
conjunction with an existing oil or gas boiler system will it be
piped in parallel or in series? The answers to these and other
questions can be determined by talking to your certified dealer
or a qualified HVAC or plumbing contractor. This will insure
that the boiler is installed and piped to accommodate your
needs and expectations.
Consideration must be given to the venting as well as electri-
cal and clearance requirements. (Clearances must be main-
tained to combustibles and also for service)
After the boiler is set into place the venting can be done.
Make sure fans are not used in the fuel storage area, unless they
are installed so as not to create a negative pressures in the room
where the solid fuel burning appliance is located.
1. Install the control board cover as well as the access
cover located on the feeder cover.
2. Install the spring handles provided with the unit on
the ash door, firebox door and the heat exchanger cleanout rod
handles. (Fasten handles by turning them counterclockwise
and pushing inward simultaneously).
3. Install 1/2” MPT boiler drain in the fitting as
shown.
Note: Use teflon pipe thread sealant or teflon tape on
ALL threads before connections are made.
4. Install 3/4” MPT pressure relief valve as shown.
5. Install the 1/2” MPT aquastat well in fitting as shown,
then place aquastat in the well and fasten with a zip tie.
6. Install the 1/2” MPT temperature/pressure gauge in
fitting as shown.
7. Locate and install outside air temperature sensor. Lo-
cation of this sensor should be on the north side of the home
or building and out of direct sunlight. Use the cat cable sup-
plied with the boiler to attach sensor to the terminals located
on the hopper. (Place at the back side just above and to the
right of the main power connection box) The wires can be
connected to the sensor with the connectors supplied. Wire
nut or butt splice connectors could also be used. The connec-
tions at the boiler can be done with the two 1/4” female push
on connectors supplied.
8. Fasten conduit to the ash base with the clamps
provided.
Assembly
Floor Protection:
The striped area indicates the minimum required floor protec -
tion area if the PB105 is going to be placed on a combustible
floor. It requires 30” X 55” of non combustible floor protection
as shown below. 6” of the floor protection must be in front of
the boiler as shown. Flooring must be a minimum of 26 gauge
sheet metal. Floor protection must also be provided under any
horizontal run of vent pipe equal to the outside diameter of
the venting plus 2” to each side.
Example: 4” type “L” or “PL” vent pipe has an outside di-
ameter of 4-1/2” + 2” on each side equals a protected floor
area of 8-1/2” wide underneath the horizontal run.
After assembly of the flue tunnel weldment, combustion
blower assembly with wiring and heat shield, the boiler can
now be installed.
