CHECKING FOR LEAKS

- To check for leaks, make up a 50/50 solution of dish soap and
water. Apply this solution to all gas connections. If bubbles
appear, there is a leak. If a leak is found, turn off the gas supply,
and re-connect the leaking connection. If the leak persists after
several tries, contact Pinnacle Customer Service at 215-891-
8460.
- The installation of this heater must meet all local codes and/or
gas utility requirements. In the absence of local codes, the
National Fuel Code ANSI Z223.1 should be followed.
- The minimum clearances to any combustible construction mate-
rials must be maintained at all times (See Page 3).
VENTILATION
CAUTION Always provide a fresh air opening in the heat-
ed space of at least three square feet (2,800 sq. cm.) for each
100,000 BTU/Hr of heater output. For example, a
MH-150V-GFA will require:
- a two-car garage door open 6 inches, or
- a single car garage open 9 inches, or
- two thirty two inch wide windows open 15 inches.

TEST FIRING THE HEATER
Test fire your construction heater following the lighting instructions
applicable to the gas control system employed.
Leak test all gas connections with 50/50 soap and water solution
prior to start-up. Soap bubbles indicate a gas leak. DO NOT use a
match or flame to test for gas leaks.
NOTE: Heater surface temperature must be cold before initiating
service, cleaning or storage.

STORAGE

Always disconnect the heater from the LP cylinder before putting
the heater into storage. If for any reason the heater is to be
stored indoors, the tank MUST be disconnected from the LP
cylinder, and the cylinder stored outdoors in a well-ventilated
area, out of the reach of children, and in accordance with the
Standard for Storage and Handling of Liquefied Gases,
ANSI/NFPA 58 - latest edition. The plastic valve plug or valve
cover supplied with the cylinder must be re-installed on the valve
to protect the fitting from damage.
Never store an LP cylinder inside of a
DANGER
building, or near any other gas or oil
burning appliances.
NOTE: Installation and repair of this heater should be done
by a qualified service person.
