MAINTENANCE

WARNING: THE STEAMER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING

OR SERVICING THE STEAMER.

WARNING: THE COOKING COMPARTMENTS CONTAIN LIVE STEAM. STAY CLEAR WHILE

OPENING EACH DOOR.

WATER TREATMENT SYSTEM

A water treatment system is recommended for steam generators. Refer to your supplier's manual for

normal maintenance procedures for proper scale-free operation recommendations.

BOILER BLOWDOWN

At least once daily, after the steamer boiler has been in operation, press [ O ] to blow down the boiler.

BOILER PRESSURE RELIEF VALVE

At least once every day, check the pressure relief valve to verify that it is functioning properly. The

valve is located on the top left side of the boiler (Fig. 3 or 4, page 17). Trip the pressure relief valve

when the steam gauge shows 4 psi or above. When steam escapes, release the valve.

DOOR GASKETS — VHX24, VHL2 & VHL3 SERIES STEAMERS

If the door gasket is nicked or cut, it must be replaced. Damage to the gasket sealing surface will cause

steam leakage.

If a leak occurs in one corner only and the gasket appears serviceable, turn the stainless steel screw

on the gasket plate adjacent to the leaking corner one-half turn counterclockwise. Do not attempt

excessive turning of screws since misalignment of the door is possible. If the door is misaligned, call

your local Vulcan-authorized servicer.

WATER LEVEL GAUGE

Check the water level gauge sight glass daily. The correct water level is approximately 1" (

2.5 cm) of

water visible in the water level gauge sight glass. Extremely murky water in the sight glass indicates

bad water conditions. The boiler should be blown down. If conditions persist, have the boiler inspected

and cleaned by your local Vulcan-Hart servicer.

FLUE

Annually, when the steamer is cool, check the flue and clear any obstructions.

INSPECTION OF BOILER INTERIOR

An access plate to inspect the boiler interior is provided for the state boiler inspector and authorized

service personnel. The frequency of boiler inspections may vary from state to state, but are generally

required every 12 months. Each time the boiler access plate is removed, the gasket must be replaced

with a new gasket to prevent leakage.
