combustible materials, especially papers and rags.

: This furnace uses an automatic hot surface ignition control. NEVER

try to ignite gas manually.

: f the temperature rise exceeds 75°F GMD2-60 / 85°F GMD2-80 , the

heat exchanger may fail voiding the heat exchanger warranty resulting in

property damage, personal injury or loss of life.

: Burner adjustments must be confirmed by instrumentation. Failure to

use accurate or calibrated instrumentation to setup the burner may result in

reduced efficiency, sooting, and/or the production of hazardous carbon

monoxide gas.

: Any attempt to relocate safety controls or replace safety controls with

a control that is not approved or incompatible, may result in personal injury,

supply during pressure testing of the gas supply system at pressures in excess

of 1/2 PS G or 14.0 inches W.G. The furnace can be isolated from the gas supply

by closing its manual shut off valve at test pressures equal to or less than 1/2

PS G or 14.0 inches W.G.

: Copper and brass tubing and fittings (except tin lined) shall not be

used if the gas contains more than a trace (0.3 grains per 100 cubic ft.) of

hydrogen sulfide gas. Check with your gas supplier.
