Preparing Your Kettle
This portion of the manual will explain how to mark and drill your kettle to install the
HERMS coil. If you have a kettle that has been pre-punched please skip this step.
Install the HERMS coil on the opposite side of a whirlpool fitting.
We recommend the coil placement be with an 8 inch arch length to the left or to the
right from the front face of your BoilerMaker™. As shown in
Fig. 1.
Each kettle has a specific recommended placement for holes. The placement of the
HERMS coil will accommodate room for the BoilCoil™ and other Kettle accessories.
Refer to (Fig. 2) and the chart below for placement.

Mark the kettle with your measurements and use an automatic center
punch to indent the location to guide the drill.
Warning:
Always follow manufacturer instructions and safety precautions
when using hand and power tools.
After marking the kettle with the automatic center punch, use a 3/16” drill
bit at moderate speed to make a pilot hole at each center punch mark. Ex-
cessive speed will damage dill bits quickly. Make certain the center punch
marks are indented deep enough to prevent the drill bit from moving off
the mark when you start drilling. If necessary, use the automatic center
punch multiple times to increase the depth of the indentation.
Use a step drill and enlarge the hole to 13/16” as shown in
Fig. 3
. Step
drills are available through most hardware/home improvement centers or
through McMaster.com (part# 8841A24 or 89315A42 for TiN coated).
Alternately, a 13/16” knockout punch (McMaster.com part 3449A999) can
be used.
