Burner applications
Follow all instructions in this manual, the primary control data sheet and the
appliance manual.
Adjust the nozzle selection/firing rate if necessary due to positive overfire pres-
sure and/or altitudes more than 2,000 feet above sea level. See the NOTICE
under the Ratings information at right. Where appliance application information
is available, the recommended firing rate and burner information will include
appropriate adjustments for positive overfire pressure and recommendations
for high altitudes. Follow the appliance manual guidelines when available.
Damage or shortage claims
The consignee of the shipment must file damage or shortage claims imme-
diately against the transportation company. See the NOTICE on page 1 for
burner carton information.
When calling or writing about the
