4.5.1.3 Parallel Installation and Clearance
NOTE: The information provided below can only be used as a general guideline. Designers must consult their
countertop suppliers when designing the appropriate support structure and clearance for the countertop and the
installation.
 Countertop Material and Spacing Requirement
For structural strength and protection against water penetration,
we recommend the followings:
 For stone countertop, keep a minimum gap of 4” [101.6mm]
between cut-outs and provide reinforcement beam in-
between units.
 For other countertop materials, the glass-tops can be put
side by side, and the joints between glass-tops must be
sealed with silicone to ensure the installation is water-tight.
o A 4mm gap between glass-tops for silicone is recommended (Option 1). However, if no gap is
desired for the installation, silicone sealant should be applied underneath the joint (Option 2).
Ensure all NSF 4 requirements for food safety are met. (HO IN 3200 Heat Plates shown as an
example.)
 Heat Plates Configuration and Spacing Requirement
The Heat Retaining Plates can be installed in a variety of arrangements. Some examples are:
 (A), (B), (C), and (D): The plates are placed in a row or in a square, with gaps or without gaps.
 (E) and (F): When installing two or more HO-IN units (each with one or more Heat Retaining Plates), a
minimum gap of 75.0mm/ 2.95” between the edges of glass is required in between the groups of
Heating Plates. (HO IN 3200 Heat Plates shown as an example.)
