Powermate P1204 - Manual (Page 15)

15 200-2667
Units are tested with natural gas before they leave
the factory. If natural gas is to be used, no adjustments
are required.
When supplying natural gas as the operating fuel,
provide fuel with a minimum of 1000 BTU/ft 3 at inlet
pressures between 6" and 11" of water column (4 - 6
oz). Failure to meet these minimums will cause the
generator to run poorly and/or may limit output to values
below nameplate value. If fuel with these qualities is not
available, contact the customer service center.
Refer to the Fuel Consumption Table on page 14 for
fuel flow requirements for the unit installed. Size all
feeding piping to deliver sufficient flow above the
minimum pressure of 6" water column (4 oz).
Per the National Gas Code (NFPA 54 - ANSI
2223.1), a manual shutoff valve in the fuel supply line
to the generator is recommended.
In cases where liquefied propane vapor is selected
as the fuel of choice, insure fuel delivery in the gaseous
state, with a minimum energy content of 2500 BTU/ft3,
at inlet pressures between 6" and 11" of water
column (4 - 6 oz). Fuel below these specifications may
cause improper engine operation and/or failure to deliver
rated generator output. Size all fuel system plumbing to
provide fuel flow as given in the Fuel Consumption
Table on page 14, at a minimum pressure of 7" water
column (4 oz).
After completing external supply connections, follow
the instructions listed below to change over to LPG.
1.
Remove the front panel by inserting the key into the
locks located on top of the panel. and turn 1/4 turn
counterclockwise to unlock. Lift the panel up and out
of the base and set it aside.
2. Remove the air filter cover (A by turning the air filter
cover nut (B) counterclockwise.
3. Remove the air filter (C).
4. Remove the 3 bolts (10mm) (D from the air filter
base (E) and set it aside. Note: be careful not to drop
the bolts into the carburetor.
5. Loosen the fuel hose clamp (F) and remove the fuel
hose (G).
6. Insert the orifice (H) (included) and tighten by
turning clockwise.
7. Put the fuel hose and clamp back on and tighten the
clamp.
8. Place the air filter base back onto the carburetor and
tighten the 3 bolts.
9. Place the air filter back onto the center stud.
10. Replace the air filter cover and air filter nut and
tighten.
11. Install the panels back onto the generator by placing
the bottom of the panel onto the base and pushing it
up into place. Lock the panel by inserting the key into
the locks and turning 1/4 turn clockwise.
