Routethe electrical cables through them and insert the sensors in theirwells.▶ Fix the control panel to the boiler casing using the screws provided.▶ Fit the front side panels [12] and [8] and rear side panels [14] and[6] over the boiler frame [10] and to the top side beams.▶ On models 800 to 1550, also fit side panels [13] and [7].▶ Secure the side panels in place using the top cross beams [19] andthe screws provided.▶ Fit the top rear panel [17], the bottom rear bracket [15] and then thebottom rear panels [16] and [18]. Fit the front top panel [5].▶ Fit the top panels [1], [2], [4] and [3].Control panel may be fitted on either side or top panel ofboiler.▶ Finally, fit the front trim panels [11] and [9].Smaller models (160/220/290) have only two toppanels, one over the right and one over the left of theboiler.6 720 805 218 (2013/02)SB625WS/SB745WS
