required to comply with international safety standards like CE and RoHS. Key Technical Specifications
Maintain at least 12 inches of clearance from combustible materials on the top, 6 inches on the sides, and 24 inches in front for servicing.
Because this is a high-power, flow-activated electric appliance, all electrical and plumbing connections should be performed by qualified professionals.
