Safety Instructions
MARSHALLTOWN’S Melter Applicators
Read Before Operating
IMPORTANT: Safety precautions must be observed while using all MARSHALLTOWN equipment. Failure to follow
instructions can result in personal injury or damage to the equipment. Reasonable care must be used at all times.
Keep applicator at least six feet from combustible material. Remove product to be applied from the box and load it
into the kettle. If product has plastic bag, it will melt into heated product when stirred.
Remove torch from kettle before lighting.
Warning!
Never allow torch to fire in an empty kettle. Turn regulator to 8
PSI to light torch. After lighting torch, insert into the kettle heating chamber on low pressure without smothering out
the flame. Inserting torch when flame is running full will likely smother flame before the updraft begins. If that
happens, turn off regulator, remove torch from chamber and wait five minutes before re-lighting. This will allow for
any unburned gas to vent, making it safe to re-ignite the torch.
Position the torch in the center of the burner chamber, making sure to remove any obstacles or obstructions. As
the torch starts to heat the chamber, the updraft will allow you to increase the flame intensity to the desired level.
Heat penetrates the block of material slowly. The MARSHALLTOWN applicator is designed to draw off liquid for
use as soon as the pouring temperatures are reached. (See manufacturer’s recommendations for material you are
using). For the best results, material should be used as it liquefies. Frequent stirring will speed melting rate. High
flame or extended heating of some materials over 400 degrees F can adversely affect the elastomeric polymers.
Warning!
Never allow material to exceed 400 degrees F. Flashing can occur when the temperature exceeds 400
degrees F. Regular operation temperature can be achieved with half the normal flame. If material becomes too hot,
remove the torch immediately and allow cooling to a safe temperature. If flashing does occur, close cover if open,
turn off gas, remove torch from chamber and allow cooling.
Warning!
Never use water on a hot applicator fire. Only use an approved fire extinguisher rated for oil fires. You
should have one of these available at all times when using the applicator.
There is no need to drain the kettle at the end of the day, but it is easier to start the next day with minimal left over
material.
Warning!
Never allow torch to fire in an empty kettle.
If the vent holes are covered while the torch is operating, the updraft will be blocked, extinguishing the flame.
Cover the applicator when not in use to prevent water from collecting in the pan.
After each use inspect hose, regulator and torch for unusual wear, cracks and or blockages. Repair and/or replace
as needed.
