4.4.3 Parallel Installation
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.
 Heat Plates Configuration and Spacing Requirement
Depending on the countertop material and support structure, the Heat Retaining Plates can be installed in
parallel with gaps in between plates ((A) below) or without gaps in between ((B) below). All the exhaust
outlets are on one side and the air intake openings are on the opposite side. See bottom view in section 4.4.1
Dimensions.
 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/IN3200 units shown below as an
example)
