Instructions / Assembly

Condensation Collection System – This boiler is a high efficiency boiler, and will produce condensate. The collection system has a

float switch which monitors the condensation level and prevents condensation from backing up into the combustion system. Inside the

collection system there is a built in trap which seals the combustion system from the connected drain. This condensate should be

neutralized to avoid damage to the drainage system or piping.

Outdoor Sensor – The outdoor sensor monitors outdoor temperature and adjusts boiler set point to provide greater efficiency.

0-10 Volt Input – Allows Installer to connect a BMS (Building Management System) to control the boiler.

Condensate Flue Check System – The check system prevents exhaust from the heat exchanger from backing up into cabinet.

Pump Service Mode – Allows manual operation of pumps to commission system and check pump operation.

The Vision II System (Optional) – Allows the user to supply mixed temperatures in up to eight zones. The Vision II system controls the

temperature to each zone by employing three way mixing valves. The Vision II also controls the output temperature of the boiler to

assure accurate temperature delivery to all connected zones.

PART 3 – PREPARE BOILER LOCATION

Carefully consider installation when determining boiler location. Please read the entire manual before attempting installation. Failure to

properly take factors such as boiler venting, piping, condensate removal, and wiring into account before installation could result in

wasted time, money, and possible property damage and personal injury.

A. BEFORE LOCATING THE BOILER

Incorrect ambient conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the boiler installation

location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or

death.

Failure of boiler or components due to incorrect operating conditions IS NOT covered by product warranty.

1. Installation Area (Mechanical Room) Operating Conditions

 Ensure ambient temperatures are higher than 32

F/0

C and lower than 104

F/40

 Prevent the air from becoming contaminated by the products, places, and conditions listed in this manual, Part 3, Section F.

 Avoid continuously high levels of humidity
