Practical installation tips that prevent callouts:
Do not block the front grille or kick-vent (if fitted). Keep it clear of mats, packaging, and dust build-up.
Avoid sealing the unit into a closed cupboard. If it must be built-in, use louvred/vented plinths, vented doors, or high and low vents so heat can leave the cavity.
Leave breathing room behind and above where possible and avoid hard contact with insulation, cardboard, or soft materials that trap heat.
After install, do a quick check: if the cavity becomes noticeably hot during service, ventilation is likely insufficient.
Always follow the clearances in the Unifrost manual for your specific model where stated.
