HN SERIES
1. CHECK OIL AND FLUID LEVELS: Check pump oil by
locating the oil view window and fill to the red dot.
2. INSTALL LEGS TO BASE. Legs are required for safe pilot
operation and reduce riskof fire. The HN Legs include
forklift fork clearance slots to allow leg installation after
the HN is removed from the pallet. To reduce risk of
serious injury, always block load mechanism in place
before working:
3. CONNECT HOSE AND GUN ASSEMBLY
4. CONNECT THE WATER SUPPLY & TURN WATER ON:
Maintain an adequate supply of water using a ¾" I.D.
steel pipe with a pressure between 25 and 60 PSI. Burner
power switches should be off before starting. Do not run
dry for longer than one minute.
5. NATURAL GAS/PROPANE GAS: Connect gas supply
using appropriate shut off cock and recommended gas
plumbing procedures, including the use of a soap or leak
detection solutionon all fittings.(Contact your gas
supplier). Note that a Draft Diverter is not included as a
standard feature with the machine. Draft diverters are
required on HN models for better heating efficiency and
improved pilot ignition when cycling gun.Gas regulator,
gas and water supply lines are not included with the
machine.
OPERATION:
1. STARTING:
Connect power supply and ensure that all wiring connec-
tions and voltages are of sufficient rating to comply with the
equipments requirements. Turn pump power switch on.
