2.6 HOOD ASSEMBLY
See Drawing # BP00000218
1. Place hood assembly (ITEM #3) on boiler with
the stack hole facing the back of the boiler.

then into the exhaust outlet on the boiler.
5. There are 4 holes located on the sides of the hood. Insert (4)
¼” quick release pins (ITEM #2), through the hood into the
cabinet until the pin is locked in place.
6. Secure & seal exhaust venting. See section 2.4
When constructing a venting system from CPVC, use only CPVC ASTM
F441 Schedule 40 pipe & ASTM F439 Schedule 80 fittings. Cement and primer must conform to
ASTM F493.
Failure to comply may result in failure of venting system. This may cause severe injury or death.

2.7 HOOD SUPPORT
1. When working on the back section of the boiler the hood can be raised and supported by the
hinged top section of the boiler. This is similar to the hood of a car and prop-rod support.
2. Remove the 2 rear quick release pins only.
3. Remove the screws holding the rear top hinged section of the boiler.
4. Raise the hood until the top section can be raised and placed behind the angle supports, slowly
lower the hood until it is supported by the top section.
For further instructions on installation see MACH®C750-C1050 Installation
& Owner’s Manual.
Be sure to correctly support the hood using the hinged boiler cover as a
prop engaging the angle supports inside the hood. Failure to do this could result in the hood falling and
may cause severe injury or death.
Remove the 2 rear quick release
pins only! Set hinged top section
behind “L” brackets on the hood
and slowly lower hood until it is
supported by the top section.

3 Maintenance
The MACH®outdoor boiler requires maintenance as described in MACH®Installation & Owner’s Manual
(latest edition) as well as the additional maintenance listed below.
General Warning
These additional maintenance items should be performed monthly.
1. Check for flue gas recirculation into the air inlet. Flue gas recirculation indicates that the vent is
not installed properly for local conditions.
2. Check for freezing of the condensate lines. Frozen lines will result in boiler malfunction. Operation
of the boiler in cold temperatures may require the use of heat trace lines for the boiler condensate
trap and drain.
3. Check for inlet air box, vent and safety relief valve obstructions due to outdoor debris such as but
not limited to, leaves, insects, snow, branches and other blockages.
